Part 4 - Learning the Open Triads
Voice leading is the linear movement of individual melodic lines or parts, their interaction leads to expressed harmonies. In other words, voice leading allows us to understand where voices want to go, by considering where they come from and what everybody else around is concurrently doing.
Smoothness and Indepenence
The primary interest in voice leading is to maximise smoothness and promote the independence of voices. These virtues of part-writing are satisfied when the voices move as little as possible and in different directions.
Considering these goals, we derive the following straight forward rules:
Common Note Principle; If two chords have a note in common, try to keep it in the same voice.
Contrary Motion; If not or for some reason you don’t want to keep it there, make sure that some of the voices move in different directions.
Make sure that you don’t cross voices - avoiding large jumps helps.
Three Baisc Voice Leading Rules
Agustin Barrios' Preludio Saudade from La Catedral is a perfect example of voice leading, by studying just a couple of measures, it completely demonstrates the application of these rules.
La Catedral - Preludio Saudade; Measures 10-11 and 19-20.
Diatonic Progressions
Let's examine the possible diatonic root progressions and their voice-leading options:
Chords that their roots are a fourth or a fifth apart have one common tone. Try to keep it in the same voice but if you don’t want, make sure that some of the voices move in different directions.
Chords that their roots are a third or a sixth apart have two tones in common. You can keep one or both at the same voices, or make voices move in opposite directions.
Chords with roots a second or seventh apart don’t have any notes in common, so your only option is to move all voices in different directions.
Voice Leading in Diatonic Progressions
These rules are mere guidelines and should never obstruct musical expression. Most great composers historically operate on the frontier of what is considered acceptable at any given time. It is the responsibility of the thoughtful composer though to understand, internalise and analyse the voice leading principles in part-writing in addition to important musical works.
Play and listen carefuly the following voice leading example, analyse the linear movement of the voices. Finaly, apply these simple rules to other progressions.

Parallel Movement in Instrumental Writing
Parallel movement is generally avoided as it takes away the individuality of the voices, but in instrumental writing, it can be an effective device for underlining a melody with a greater sense of cohesiveness and density. Claude Debussy and Maurice Ravel, architects of the contemporary music, used parallel melodic harmonies extensively; but there are examples of parallel movement even in Bach.
In a contrapuntal context, parallel harmonies may provide contrast but should be only used sparingly.
An example of paraller movement can be found again in Agustin Barrios' La Catedral, in the second movement this time.
La Catedral - Andante religioso; Measures 3-4.

30-minute Classical Guitar Warm-up Routine
The main reason for setting up and following a regular warming-up routine before each practice session is to you avoid muscle and tendon related injuries. A successful one will also assist in your technique development and allow you to increase your playing consistency.
Be careful not to overdo it though, you don't want to wear down your fingers before your session even begins. A common mistake among guitar students is to spend most of the practice time with technical exercises, neglecting polishing up repertoire.
By focusing on each exercise for only about 3-4 minutes, alternating hands and focus area, you can manage to tire your fingers just a little, while maintaining physical and mental stamina for the basic work-out.
Additionally, you want to work your fingers on a variety of techniques and movements, to ensure a balanced outcome, with the additional benefit of having worked and polished the basic - and most important - techniques that the classical guitar repertoire requires.
Before you begin, keep in your mind that, accuracy is extremely important. Therefore, practice at a slow and comfortable tempo, stay focused and pay attention to your tone production quality, and efficiency of movement.
ABS: Always Begin Slowly
Start with some of the basic Right-Hand attack techniques on a single string.
Although "im" is mostly used for scales and melodies, a fit “a” (RH) finger, as well as an agile “4” finger (LH), gives overall balance and control to the hand - therefore don’t skip on practising the “ma” variations.
Also, try different strings.
After a few minutes, it is time to let the RH hand rest and concentrate on the LH, slur exercises are very helpful. Pick a scale practice hammer-ons.
Keep all the fingers as close together to the fretboard as possible, and aim for a quick and accurate attack. Slurs are all about accuracy, strength is over-rated.
More RH picking exercises on a single string, this time triplets will guide us to practice sequential attacks with three fingers.
Triplet accenting slurs for the left hand. Make sure that the tone of all three notes is similar - pay attention especially to the pinky as it usually the weakest one.
Its time to introduce string crossings for the right hand, these will prepare your RH fingers for more realistic - real repertoire - requirements.
Practice descending slurs with pull-offs. I like to keep working on the same scale throughout the warm-up routine.
Tremolo is an elusive technique for many guitarists, perform these sequences, and emphasise the first finger to gain more control. Remember, repetition is the key to success.
Left-hand triplet descending slurs. Focus on the pull-offs, each note should have the same volume and tone.
We are all Drummers: when practising right-hand Patterns, like these arpeggio sequences, I usually mute the strings with my left hand, to better judge the accuracy of the individual hits.
Mixed slurs can be very rewarding, these are some examples but try to experiment with different one or two strings mixed-slur sequences.
Remember, none of these exercises is fully comprehensive, I could (and do) easily spend more than 30 mins just on each topic individually, but that's not the purpose here. So, if you have trouble with a specific technique/exercise or want to elaborate more, find a place to fit it into your regular practice routine.
The Rasgueado exercises are useful even if you don't plan to play any flamenco, they give strength to your finger and flex them to the opposite direction for better balance.
Work on short bursts of speedy ascending lines, so that you can synchronise both hands and practice scale lines that might come up in your repertoire.
Four finger Rasgueados for more fun.
And lastly, short bursts of speedy descending lines. Push your tempo limits but don't forget that accuracy is the King.
Parting thoughts
As pointed earlier, tone production quality should always be a concern, as well the accuracy and efficiency of the movements. Try to stay focused throughout the warm-up and the rest of your session. Never practice without concentration, it leads to uninspiring performances. And don't practice without intention, because it leads to incoherent playing.
This routine might seem somewhat excessive, but the length of each repetition can be adjusted to realistically match your time. Some of the variations can be skipped, but try to cycle through all of them at decent intervals.
It is most essential to follow and repeat all the exercises a few days before a recording session or a concert, doing so, you will get to be at the top of your game.
Purposeful Practising
A Personal View on the Art of Practising the Classical Guitar
One of the most common issues that I encounter among intermediate and sometimes even advanced guitar students is that they don't know how to achieve the most with their practising. They usually try to memorise a piece, then play it from the top a few times, and move on to the next.
This approach is not what I consider purposeful practising, as it doesn't lead to the mastery of any of the aspects of performance. This epidermal handling of repertoire hinders the chances to unlock hidden details. In other words, you ought to become an expert!
Here are the steps I take when I'm learning a new piece.
The First Read
I usually read the whole piece once or twice, not only this helps to improve and maintain my sight-reading skills in the long run, it allows me to have a broader idea of what the piece is.
Finding Fingerings
After the first read, I make fixed and deliberate string and fingering choices, measure by measure and phrase by phrase. I evaluate the different options based on the character of each voice, the ability to connect with the previous and next phrases, and by ensuring finger independence at its maximum.
I take notice on published fingering suggestions, but I don't rely on them as I almost always have to change them.
Notes, Rhythms, and the Choreography of the Fingers
I go through every measure with a metronome to verify that all my notes and rhythms are correct, and make sure on the deliberate and purposeful movement of my fingers on the fretboard. I repeat the part I'm working on as many times as it is needed, establishing an exact finger choreography.
Confidence
Slow, deliberate practising and repetition are the devices that build performance confidence. What you want to avoid is to use the same tools to reinforce a faulty technique.
I practice at a comfortable tempo; from a couple of measures to a full section, and finally the whole piece. My objectives are clear tone and perfect delivery. When I make a mistake, I start over!
Building Speed
Practising with a metronome keeps us in time, and creates a reflection in our brains of what the piece is like, and how our fingers should be moving to achieve that. Therefore when it is time to start working on speed, I start at a very comfortable tempo and with small increments (around 4 to 6 BPM) I practice until the point that the piece starts to fall apart. I always push a little further than that, but at the last playthrough, I return to a comfortable tempo.
Interpretation
When notes and tempo are in place, it is time to work on phrasing and dynamics. An awfully important nuance of performance as it expands our capability for individual development, and the capacity to communicate deeper emotions with our music. Yet, it is probably the aspect of music that is the most difficult to teach, and often teachers and players don't contemplate.
Writing about phrasing and dynamics in music is like talking about a painting or a picture, but I can give you some of the processes that guide me to improve my interpretation skills.
First, I read about a specific epoch and learn as much as I can about the individual composer that I'm studying. It doesn't mean that I have to restrict myself to a clichéd way of performance; on the contrary, with a greater insight into what a piece is about, we become freer to make deliberate choices and shape or phrases.
An equally important step is that I try to listen to as many performances of this piece as I can find. I try to listen to all the small details that we generally don't pay so much attention and make notes. I ask questions, make notes. For music adapted from other instruments, I like to listen to performances on the original instrument.
The key-words here are to become informed, purposeful and conscious of all the choices you have to make to shape your interpretation.
Practising Performance
Practising and performing are two different concepts with distinct purposes. While I practice to learn how to move my fingers more accurately in an almost mechanical and unconscious motion, to minimise mistakes, and determine the minutiae, hoping eventually to become a master of a work. The focus in performance is to carry out in a focused manner the essence of a piece, have a concise and nuanced meaning, and not to allow small mistakes to destruct the cohesiveness of the piece.
After breaking up all the individual elements for better control of phrasing and dynamics, it is time a put it all together. In consequence, I conclude every practice session with an actual performance of the piece I'm learning.
I treat this final segment as a legitimate performance, one that takes place in front of an audience. If a mistake occurs, I attempt to minimise its significance. I don't stop, but I carry on until I play the whole piece - sometimes the whole programme that I decided to play. I record my practice performance for critique!
Revision
On my next practice session, I start working on the parts that were not executed well, try to understand the technical difficulties or problems that might cause that. I attack the parts in question and attempt to find solutions.
The Informal Recital
Even if you are not yet a performing guitarist, or might not even aspire to be one, I recommend that you give short informal recitals to your friends and family. Not only it is a fun way to spend a Sunday afternoon, but also nothing builds confidence in your skills more than the sound of warm applause.
Be mindful, play only the pieces that you can execute adequately; nobody wants to see you struggle with a difficult piece that is way out of your level (yet). Even if that means that your recital should only be 5 minutes long, eventually you will build on that. Lastly, don't forget to offer them a glass of wine or two before your recital.
Closing Thoughts
Practising any instrument requires a lot of time and effort, and the guitar is no exception. If you take action to make your practising more focused, purposeful and efficient; your playing with developing in a similar deliberate manner. One that leads to the immensely rewarding experience of masterfully playing the guitar.
Practising Triads & Inversions
An Intensive Journey to Demystifying the Fretboard - Part 3
If you haven’t read yet, make sure to check the previous segment of the series:
Part 2 - Understanding Double Stops
Triadic harmony is so profoundly embedded into the western culture that, even when played out of context, their sound is so powerful that our souls, minds and bodies still revert to their meanings.
Therefore, our next stop in the journey to the further demystification of the fretboard could not be anything but the Triads; regardless of how well you think you know them.
The Triad
A triad is a set of three notes that can be stacked vertically in thirds.
G Triads in Root Position.
Triad Inversions
When any note other than the root is in the lowest voice, the triad appears to be in inversion. Inversions of triads have distinct qualities and attributes.
G Triad Inversions
All Inversions
The first step is to learn the Triads and their Inversions in all positions across the different string-sets.
G Triad Inversions - All String Sets
The Diagonal Guitar
After getting comfortable with these, the next step is to practice the Triads in a diagonal array - starting on the lowest note available which is not always the root. This approach provides the most effective way to have the whole fretboard at your disposal at any time.
G Triad Inversions in a diagonal array.
Diagonal Diatonic Triads
Once you start feeling comfortable with the G major Triad, apply the same approach to all diatonic triads in the key of G major.
Practising Triads in Pairs
Triads are almost never found alone, they usually act in cooperation with other sonorities that precede and follow them. Much like all music anyway; we experience sound in time and we give meaning to it by appreciating how it unfolds.
Practising triads in pairs is a useful exercise to realise how harmonies connect as well as a way to force ourselves to practice more than one things at the same time.
For now, practice diatonic triads that their roots are:
A fourth/fifth apart - these have one note in common
A third/sixth apart - these have two notes in common
A second/seventh apart - these don’t have any notes in common
