I wrote this for the Tonebase blog a while ago and thought I’d share it here. Hope it helps!
A crucial aspect of right-hand technique is the ability to control the stroke of each finger when it interacts with the string. During this interaction, the energy of the stroke determines the volume of the note and, if well done, does not displace the other right-hand fingers in the process. This requires right-hand finger independence. To this end, I like to walk students through a series of activities utilizing a fixed right-hand finger with the focus of keeping the hand and inactive finger calm.
During the sequence and patterns, watch the right hand as carefully as possible for any extraneous or micro movements. Ask yourself whether it is possible to pare these movements down to stillness. Does the thumb stroke overwhelm the hand? Are there any fingers or combinations that are more uncomfortable or weak? Is the stroke efficient?
To start, place all right-hand fingers (p, i, m ,a) on the 4th, 3rd, 2nd, and 1st strings respectively. I recommend using a metronome (quarter note = 60).
Step 1
While keeping the inactive finger on its respective string, starting softly, play the following patterns. Go slowly and spend enough time on each pattern (a minute or two) before moving to the next one. Focus on keeping the same volume in both the thumb and the fingers that are alternating or working together. Note: a should remain fixed on string 1

Repeat Step 1 but impose the metrical accent. Think: 1 and 2 and 1 and 2 and, etc. Weak beats (the ands) should be slightly softer. For fun, drop the strong beats to the background and play the weaker beats with more energy. Watch your hand with curiosity to see how it behaves. Make deliberate adjustments until it feels groovy, balanced, and comfortable. Experiment with volume. Experiment with tempo.
Step 2
While keeping the inactive finger on its respective string, starting softly, play the following patterns. Take your time to feel. Focus on keeping the same volume in both the thumb and the fingers that are alternating or working together. Note: m should remain fixed on string 2

Repeat Step 2 but impose the metrical accent. Keep weak beats softer. Watch your hand with curiosity to see how it behaves. Make adjustments until it feels right. Experiment with volume and tempo.
Step 3
You know the drill. Take your time to feel. Focus on keeping the same volume in both the thumb and the fingers that are alternating or working together. Note: i should remain fixed on string 3.

Repeat Step 3 but impose the metrical accent. Keep weak beats softer. Watch your hand with curiosity to see how it behaves. Make adjustments until it feels right. Experiment with volume and tempo.
It is nice to follow these three steps with some arpeggio etudes.
Hope this helps you reach your musical goals!

The image I hold while playing Heitor Villa-Lobos’ Etude Nº1 is one where I am sailing above the canopy of the amazon rainforest as if it were an endless gentle green ocean. Putting this image into practice presents many challenges for the guitarist but simply having an image helps to move the fingers smoothly and with little resistance. Commanding the right-hand to execute the arpeggio to comfortably create the waves of this amazonian ocean, the crescendos and decrescendos, requires some persistence, though. And to truly master the image, it is equally important to investigate how the left hand moves from harmony to harmony, how softly we transition from chord to chord, and how the right hand waxes and wanes over the strings. Ocean waves have an inherent softness to them. To approach this quality in both hands, I’ve brainstormed a bit to list some key tips that I’ve focused on over the years:
times? This is the amount of times you would play it in the Etude before getting a break with the slurs.
Aside from the lush harmonies and hauntingly evocative melodies of Heitor Villa-Lobos’ music, the physicality of strumming or arpeggiating through all six strings, of sinking a fat thumb rest-stroke into a deep melody, of sliding all four left-hand fingers across the fretboard through diminished 7th chords produces a visceral joy unlike any other I experience when playing the guitar.
