Three Ways to Improve your Recording Space Without Spending Any Money

Let’s talk about the room - Part I

When we think about improving our recorded sound, we usually think about upgrades in gear; we lust for new microphones, interfaces, guitars, etc. We don't want to buy new things; we absolutely need them. Sometimes, we even postpone recording altogether until we have the budget for purchasing said gear. 

The harsh truth that we sometimes don't want to admit is that spending more money on gear will not fix fundamental issues. Getting a good sound in the room before we hit record is essential, as essentially, this is the sound that our microphones hear and our interfaces capture. Fix it in the mix does not apply with classical guitar recordings wherein room and performer are equally exposed.

Having used all sorts of gear in all possible situations, I rank all the elements of the recording chain in this order: guitarist, guitar, room, microphones, engineer, playback system, post-production skills, preamps, converters, cables. Leaving everything else aside, in this article, I examine a few ways to get the best out of a typical residential room without spending any money.

Disclaimer - room treatment can be approached from a more technical standpoint which I plan to discuss here in the future. Contrarily to what the vendors of acoustic panels will say, household items can be used as a pragmatic alternative, even more so considering the singular commitment of a classical guitar recording space.

First. The sitting position.

Sometimes out of being lazy or just practical, we set up everything as is and keep the room as we would normally use it, especially if we don't have a dedicated music room. Considering the degree that the room affects the recorded sound, searching for a suitable sitting position should not be overlooked. 

Before all else, when I enter a new space for a session, I try to figure out the best sounding position in the room. This habit applies both for on-location to home recordings and even concerts to some degree. I'm not getting into detail about on-location recordings and big spaces now, as this goes beyond the purpose of this text.

I have assembled a few guidelines to help you search for the perfect sitting position in your room but keep in mind that every room has unique sound properties.

First of all, you want to avoid sitting close to the walls and most definitely steer clear of the corners; the build-up of low frequencies and the early reflections will cloud the direct sound of the guitar. Also, the centre of the room is far from an ideal sitting position, especially in a room with parallel walls.

In an ordinary rectangular room, if possible, you'd want to sit alongside the long walls about three-fourths to two-thirds of the length of the room. In addition, I find that sitting a bit off-centre and facing the front wall at a slight angle towards the longest distance produces the best results; this modest break of symmetry helps.

Nonetheless, you need to experiment with your space as every room is different. Perhaps asking someone else to play your guitar in a couple of different positions and try to listen is not a bad idea. If this is not possible, pay attention to the sound while you play; singing can also assist you in identifying the room modes. Moreover, you'll need to record yourself in various spots and listen critically; recording the same piece can make comparisons less ambiguous.

What you are looking for is the most balanced sound; play all notes of your guitar in sequence as well as your favourite piece, and if it gets boomy or any frequency stands out a lot, try a few different angles or move a little. If the room is untreated, which probably is, the result will not be outstanding, but in any case, it is worth finding the position where standing waves are not encouraged, then acoustic treatment can be employed.

Second. Other uses for your books.

Speaking of acoustic treatment, this goes without saying, at least to some extent. But, as our rooms usually serve (at least) a dual purpose, a playing/recording space along with a listening/production room, some compromises have to be made. Critical listening requires a controlled environment, while what makes a good room for recording acoustic instruments can be partially subjective.

I have recorded in all sorts of situations, from big halls with a vast reverberation to heavily treated studios with no ambience at all as well as everything in between, thus I have concluded that I genuinely don't enjoy playing in an acoustically dead room. Even if the captured sound in such a controlled room is somewhat easier to handle, the performance and feel of the music always take a big hit. Clever microphone placement and good post-production skills can make almost any room sound acceptable, contrary there is nothing we can do to improve an uninspiring performance.

Thankfully, the classical guitar is not the loudest instrument around, with a lot of its energy residing is in the mids and highs, so it is not impossible to minimize the small room sound signature. Whilst is more convenient to record at home, on-location recording is never out of the question; I could always visit one of the exceptional sounding halls in Berlin or elsewhere when absolute sound is required. It is also refreshing to work on other rooms.

Wherein large rooms we have to deal with diffuse sound fields, which pose their challenges anyway, small rooms suffer from early reflections and resonances associated with standing waves. Dealing with the low frequencies below 300Hz is rather troublesome as wavelengths are large and spread omnidirectionally, while higher frequencies behave more like rays.

The key here is to use a combination of diffusion and absorption strategically. Since broadband diffusers and absorbers can get expensive fast and need to be quite thick to have any effect at the low-mid and low frequencies, there is a free alternative you can use effectively: books.

Books placed on shelves create an uneven surface, forming some sort of diffuser from which sound waves are reflected in different directions. Moreover, paper absorbs some of the sound energy, so a bookshelf works in addition as an absorber.

Gather your books and build a bookshelf on the front-facing wall (in the typical control room, the front wall is considered the one where the monitors are placed, here I use the term to indicate the wall you face when you play your guitar). Use different book sizes and thicknesses, and experiment on the relative depths; this bookshelf will absorb and scatter the sound in the room while maintaining some liveliness.

Admittingly, a bookshelf won't do much to the lower frequencies, and its properties will be somewhat random. However, you probably have plenty of books in your household already, and a bookshelf is more eye-pleasing. Plus, they are nice to read from time to time.

Third. The floor.

Since the guitar hangs in closer proximity to the floor than any other reflective surface around you, bouncing frequencies would cloud the direct sound. Also, the somewhat low ceilings and small dimensions of residential rooms dictate for closer and lower microphone positioning that say a concert hall, thus heightening the problem.

To tame the room ambience to a certain degree, place a rug between your guitar and the microphones. Avoid covering the whole room with a carpet, but rather use a small to medium-sized one. 

Experiment with a few different sizes and thicknesses until you find what works in your space. Your goal is to allow the microphones to capture a cleaner sound while maintaining the room ambience. The absorption will only be effective at the high frequencies. I use a woollen rug of medium thickness that extends from just under my seating position to a bit further than the position of the microphone stand.

Closing

With the advancement in technology over the last twenty years, quality recording equipment has become pretty affordable consequently capturing compelling recordings at home is no longer impossible. However, we should not forget that the microphones capture the sound of our guitars in our rooms. So, be intentional and learn trust your ears.

5+1 Things That Will Improve Your Classical Guitar Practising

In the first part of Things That Will Improve Your Classical Guitar Practising, I touched upon adopting new habits that can boost your efficiency. The second part elaborates on the importance of being mindful in your routine.

Time is of the essence.

Music is organised sound in time. As audiences, we experience a musical performance as it unfolds linearly; one moment leads to the next. We give meaning to the notes not only by what surrounds them and is heard concurrently but also what precedes and follows.

Listening to music is a highly complicated process. Although we are intuitively tuned to understand shifting emotional states conveyed by pitches and rhythms, a well-defined sense of beat is necessary as it seems to be conformity between musicians and listeners amongst all different cultures. 

In other words, no matter how diligent was the composer when choosing the right notes and rhythms if the performer doesn't support them boldly; in that case, the music suffers.

When it comes to keeping time, the metronome is the best friend you ever had; it will never lie to you and will make sure that you respect time.

Use the metronome in your daily practice. Make sure that you understand the rhythms that the score presents to you. The key word here is understanding; solo performances don't always need to be metronomically precise. Perfect executions, metronomically speaking, depending on the style, can be uninteresting. But, if you don't learn to perceive rhythms accurately your audience will be left confused.

So, remember to keep a balance of practising with and without the metronome. Eventually, you'll need to learn how to let the phrases breath as well.

Stand on the shoulders of giants.

Sir Isaac Newton famously wrote in 1676 "If I have seen further it is by standing on the shoulders of Giants". Music might not be astronomy or mathematics, but the tradition is a well established one.

Through the aeons, teachers play the role of passing wisdom from generation to generation. And, in the age of information, books, forums, videos and blogs can give us additional insights into the music we pursue to master.

While we can take advantage of all those options simultaneously, with the danger of being overwhelmed, I would argue that nothing has more value than claiming the information ourselves. A century of recorded music gives us access the judgement, observations and vision of the great masters.

It is imperative to listen to music carefully, lots of it, various performers and interpretations. Analyse and criticise it; ask questions. Try to understand why they make the choices they do; what works, what doesn't and why. Make notes, then try to apply some of your findings to your playing.

Know thyself. Or at least try.

Psychological research suggests that we are not very good at evaluating ourselves accurately; we frequently overestimate our abilities. This is known as the Dunning-Kruger effect. The less we know, the more we think we understand; and musicians are no exception.

No matter how many times your teacher points out that your rhythm is way off, it's extremely hard to evaluate yourself objectively in real-time. Additionally, it is impossible to fix performance issues before you understand what these issues are. It is a process.

Thankfully, in our technological world, it is possible to shorten the gap between how well we think we play and how we do sound. To stare directly in the mirror and observe all our faults. We achieve that by recording our performances regularly and then listening critically. The emotional distance that is granted by becoming the audience allows us to review our playing slightly more objectively. And as we keep exercising this muscle of critical listening, we eventually learn to do it in real-time, at least to some extend.

And no, you don't need to set up a home studio, even a simple audio and video capture with your phone can have a similar effect. Admittingly, investing in some recording gear won't hurt; a pair of decent microphones and a good headphone.

A chat with the composer.

Most of the classical guitar repertoire was composed long before we were born, by composers that are not around anymore. But even for our contemporaries, we rarely have the chance to have a one on one chat about their works and intentions. In either case, they have grand us with something almost as good; the music score.

When you study a new piece of music, don't just read the notes. Study the harmonic implications, the motives, the rhythms. Break down the composition to its elements, see how they connect, ask what their purpose is. Try to understand what is their function in the micro and macro context.

Additionally, read the biography of the composer, learn about major influences, life and period. Be interested and get personal. This in-depth research is utterly inspiring and may lead to musical revelations.

Understand the notes.

"Music is a language", how many times you have heard or repeat that phrase? Well, I believe that most people don't truly understand what it means.

The most common reading of that phrase is that music can affect our feelings universally across all cultures, meaning that we can detect happiness and sadness even in unfamiliar music idioms. While that is not wrong, it doesn't even touch the surface of what makes music a fully grown language.

Pitch, tempo, rhythm, and dynamics convey shifting emotional states. In Western music, harmony gives us information about the hierarchy of pitches, their tendencies and their meanings. Even if we don't formally study music, we learn to intuitively understand these nuances by an early age with nursery rhymes, cartoon music, songs in family gatherings, etc. But, every culture has its music, and each has a language.

Study common practice harmony, study contemporary composition techniques, learn the peculiarities of different periods, learn the specifics of the culture that you come from, be interested in other traditions, and diverse musical genres. After you learn the basics, dive deep into things that got your attention, then study wide and repeat. 

Be interested in the tradition; in consequence, your playing will become more engaging and individual.

Destination.

Guitar playing is one of those things that you cannot stay still; if you stop pushing forward, you roll backwards. It takes a lot of hard work and discipline only to keep one's technique, let alone advance. Although you can set goals for yourself, there is no real destination. The journey is the reward; Music is a lifetime pursuit after all. So, don't be anxious, don't rush, enjoy every step of the way.

6 Common Mistakes When Recording the Classical Guitar at Home, Part II

Part II - Post Processing

Professional sounding classical guitar at home is not a fantasy anymore or at least achieving a recording quality that is not embarrassing to share. Affordable audio interfaces, preamps and microphones have flooded the market these last decades, with increasing performance and processing power. Rooms, recording techniques and mixing are holding us back.

In the first part on the 6 Common Mistakes When Recording the Classical Guitar at Home, I tried to encourage you to try out different microphone positions and to study your room acoustics.

The second part focuses on some of the common mistakes of beginner classical guitar recordists on utilizing a proper signal chain and achieving satisfactory results in post-processing.

Mistake no.1 - Improper gain staging 

AEA TRP2 Gain Knobs

The fear of clipping the converters leads some amateur recordists to use too little gain, resulting in recordings that are low in level. Without adequate signal-to-noise rations, these recordings will become noisy when any attempt is made to bring them at a normal level during mixing or playback. Contrarily, recording too “hot” will possibly clip the converters and can introduce nasty sonic artifacts to the audio. In either case, the recording will suffer from a limited dynamic range and high noise; attributes that we don't usually associate high-quality classical guitar recordings.

My advice is to aim between -6dB to -12dB as a maximum peak level (not average), per channel. Therefore, when you are happy with the placing and distance of your microphones, do a couple of test recordings, play as loud as you would normally do and set the gain levels accordingly. If you set the levels correctly, you will have a healthy and strong signal, but even if you (or another guitarist you are recording) eventually get carried away during the performance, you still have enough headroom to avoid digital clipping.

Mistake no.2 - Unrealistic panning

Classical guitar is a small instrument, radiating sound from a definite point in space. One of the worst choices you can make if you record in stereo (which you should) is to use a too wide panning. Regardless of if the listener is an audiophile type, sitting on his couch perfectly balanced in front of a pair of top-tier speakers, or a regular person listening to music with earbuds. A hard-panned left and right guitar will sound unnaturally wide and cloudy.

Proper panning of Stereo AB channels

A realistic classical guitar recording is one that creates a phantom image of the instrument right in the middle of the speakers, but with some space around it. Such recordings can remove the playback medium and transport the listener in the room with the player.

In typical AB Stereo scenarios, I pan one channel at 3 o'clock and the other at 9 o'clock. I fine-tune the panning according to the polar pattern of the microphones, how apart they are set, and the distance from the guitar.

Mistake no.3 - Limiting dynamics

Classical guitar is not the most dynamic instrument, and if anything, we should strive to capture as much dynamic range as possible (it starts from the player, so we should also prioritise dynamics in performance). Compressors, on the other hand, are designed to do just the opposite; minimize the dynamic information of an audio track by limiting the loudest notes and boosting the softest signal. 

The classic Universal Audio limiting amplifier

Compressors do make the initial playback sound more exciting and powerful… for a few seconds, but in my opinion, it never pays back. Some of the problems that are introduced with the use of compressors in solo classical guitar recordings are squeezed dynamics, increased noise level and altered instrument tone. 

Cross-genre guitarists employ compressors more often, as they learn that they can be invaluable in a dense mix. But I haven't found any use for dynamic limiting in a properly captured classical guitar recording.

Therefore, unless you have to deal with issues of the room or improper microphone positioning, don't use compressors on classical guitar recordings.

Mistake no. 4 - Being afraid of using filters

Many microphones feature high-pass filters, the most common are 40Hz, 80Hz and 120Hz; the same is true for some dedicated outboard preamps. But many beginner recordists are afraid to take advantage of them. The truth is that in the context of the classical guitar, not much musical information is presented at the low-end frequencies. Most of what is below around 80Hz is unwanted room rumble and weird resonances; therefore by attenuating them, we end up with a cleaner recording. Capturing what is essential and leaving out the rest. 

As low frequencies can have a lot of energy, it is preferable to cut undesirable low-end before the signal hits the converters, if possible. This tactic allows us to set the gain and levels appropriately and leads to better signal-to-noise ratios. But even if your microphones or preamps don't have any filters, you can still apply a high-pass filter in your DAW to remove non-essential information.

I also like to use a low-pass filter to remove high-end information that is inaudible, so that my audio consists of only the frequencies I can hear. A gentle roll-off of the low (below 50Hz) and high frequencies (above 18000Hz) is a good starting point. An EQ plugin with these basic filters is the first plugin I load on every track. You can read more on the article Three Most Essential Plugins for the Classical Guitar.

Mistake no.5 - Not learning how to use an equalizer

Other than the low- and high-end unwanted information that we can simply remove with the appropriate filters, undesirable resonances can occur in the audible range as well. These can be caused by the imperfect rooms that we are recording in, our instruments or our technique. Obnoxious resonances can and will distract the listener. 

Learning how to use an equalizer to detect and attenuate or eliminate such issues will make the listening experience much more pleasurable.

The best way to identify an offending frequency is by using your ears. I know that this doesn't sound like great advice, but keep reading. When you detect something that you don't like, add a bell-shaped point on your EQ with an extreme boost and search through the suspected range, like dialling in an analogue radio. 

Once you find the irritating frequency, the sound should be quite disturbing at that point, apply a notch or a generous cut with a narrow Q. Toy around with the Q value to find the sweet spot; a setting that makes the problematic sound disappear but lets the rest of the audio unaffected.

Another use for an EQ is to change the overall balance of the recording. Sometimes you'd prefer a slightly fuller recording, or there is just a bit too much low-end. Perhaps the treble is a bit piercing, or you'd like to add some more clarity and articulation. Making gentle adjustments like these are generally uncomplicated with the use of Low or High Shelf adjustments. Just a couple of dB's can make a drastic difference to the evenness and impact of our music. 

Just be careful not to overdo it, and always compare your mixes to your favourite recordings.

Finally, you can also use an equalizer to completely change the sound of an instrument and shape it to your liking. But if you've been diligent with the microphone positioning, and you like your guitar sound, you won't have to.

Mistake no.6 - Too much reverb

Placing the music into an artificial hall is a necessary lie

As I write on the Three Most Essential Plugins for the Classical Guitar article, nothing will affect the listener more than the physical space that the music takes place. 

When we record at home, most rooms are not interesting enough, and so we need to enhance their sound with artificial reverb. But it is easy to overuse reverb, as it makes everything sound "better". Or so we think when we first enter the home recording world.

Most beginner recordists tend to choose a random church preset without any consideration to requirements of the music, tempo and other aesthetic choices. The result is a flood of unnatural and unattractive recordings which instead of sounding realistic or enchanted, they feel cheap.

Learn how the Time, Size and EQ settings found on your reverb plugin of choice to fine-tune the sound the ambience. Then turn down the Mix a little bit more than what you think it should be. Lastly, compare your efforts to commercial recordings (not that those are not guilty of overusing fake church algorithms).  

Closing thoughts

Proper mixing can turn a decent recording into a great one

I hope that this article will make you more conscious of your post-processing choices. I need to write dedicated articles for the use of equalizers and reverb as there is a ton of things to discuss. 

I know that many guitarists don't want to fuzz around with plugins, but proper audio processing can transform a recording. Mixing is an art in itself; a necessary evil that can turn a decent recording to a great one. Quality classical guitar recordings are important for your audience and benefit the classical guitar community as a whole. Thus, it's definitely worth the time and effort to learn how to mix your audio. Alternatively, you may search for someone else to do that for you.

Tip: You don't have to mix every track from scratch; after all, you probably record the same instrument with the same microphone technique and in the same room all the time. Create a template in your DAW with your basic panning, filter and reverb settings. You'll still have to tweak around a bit, as not every piece favours the same settings, nor every day is the same. Templates are great time savers. 

6+1 Things That Will Improve Your Classical Guitar Practising

Playing the classical guitar can be utterly gratifying for professionals and amateurs alike; moulding unique sounds with our fingers and expressing our inner selves. Even more so, playing an instrument is a way to escape some of our everyday problems.

On the other hand, practising the classical guitar can often be frustrating; progress sometimes feels impossibly slow, and there are way too many things that need our full attention.

Adopting a new habit, or slightly shifting our mental state, can transform our practice sessions and boost our efficiency. Besides, a more enjoyable time with our instruments could only make us want to play more.

Here are a few of the things you can do to get the most out of your practice session.

Schedule your Practice Sessions

If you often postpone practising, finding yourself not having enough time for a full session. Try to organise your day better, instead of picking up your guitar every time you feel like it. Just like many other activities, set a specific time for practising, and make sure to show up on time. No excuses.

Don't Skip Days

If you can dedicate a couple of hours every day for your passion, it's excellent. But, don't skip practising for a day because you only have half an hour, thinking that it won't be enough. Decide on one thing, be it a difficult phrase or technique, you wish to conquer; gather all your concentration and dedicate your limited time on taming it.

Practice What you Can't Do - but Don't Reach Out for the Stars, yet.

I often see people with very little experience try to tackle a difficult concert piece. Usually, they try on their own for a couple of years, then frustration kicks in because they don't see any improvement, and they either quit or (hopefully) search for a teacher. 

You should always practice material that is on the edge of what you can do, but not totally out of reach. Not too hard, not too easy. By building a well-balanced repertoire when the time is right, even difficult pieces will seem effortless.

Keep an Organised Space

There is no better way to lose time and kill concentration than having to search for that Bach score you wanted to work on, a metronome, a file for your nails, etc. Keep a tight and organised practice space with everything you need for the routine available at hands reach.

Do Not Disturb!

Speaking of concentration, put your phone in silent mode! You can achieve more in 30 minutes of full concentration, than in three hours full of distractions. Unless you are a surgeon, or your wife is pregnant, you can manage to stay off-line for an hour.

Don't Practice Through the Mistakes!

A common mistake that beginner guitarists do is to keep practising the same things, and usually by repeating the same mistakes, over and over again hoping that they might eventually improve. 

What happens is that mistakes are being reinforced through repetition. Our muscles don't care if it sounds correct or not; if you repeat a movement a hundred times, that's what they'll learn. So, every time you make a mistake, stop right there and start again from the top.

If the mistake persists, work out the specific measures that need attention. Find out why your fingers want to play something different, practice slowly and correctly until you have it all down.

Slow. Down.

Playing classical guitar requires fine finger movements and coordination. Guess what, you cannot control those if you play at a relatively fast tempo. Work on your technique at a very slow tempo, one at which you can control all these fine movements to a great degree. Once you have the correct movement down, it's easy to increase speed.

Repeat - repeat - repeat

You managed to play that difficult Villa-Lobos part correct... once. You should celebrate!? Well, not so fast! If you cannot play it correct at least five times in a row, you probably haven't nailed that part yet, and chances are the when you'll have to perform the full score, the "wrong" version will creep into your performance. So, don't be satisfied with one correct repetition, and move on to the next part. Repeat as many times necessary until you can play it correctly every time!

Don't neglect to enjoy your sessions

I hope that some of these ideas will help you play this difficult piece you have been trying for some months, and hopefully make your practice a touch more satisfying. 

Don't forget, no matter your level or your goals, be thankful for what you have achieved so far. Being able to play the classical guitar is a reward in itself.
