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.
One great example of a passage providing this physical joy is the arpeggio section of Prelude Nº2. While there are a few tricks for making the left hand slide around with more facility, I’m going to focus on some possible right hand fingering solutions that have helped my students over the years.
There are three patterns to master with the first offering most possibilities. Try to work on all patterns carefully until they all feel fluid. The thumb should play through both the 6th and 5th strings. I prefer using a light rest stroke so that I land on string 4 and am ready to proceed from there.
ppimamip – This fingering seems to be the favorite for most of my students. Thumb gets overworked a bit and when it is next to other patterns the right hand has to shift its position across the strings increasing the margin for error.
pimaiiip or pimaiiii or ppimaaaa – These options work well but require careful practice to sound precise. I prefer the first for clarity and I cannot get the last to work for me but have seen other guitarists use it successfully.
pimamami – This fingering can work well as m is the longer finger and can reach out of a stable hand position for the first string.
pimapima – This one is pretty straight forward but requires a clear movement from the thumb to move through two strings as if it were one.
mipmipmi or aipaipai or amiamiam – The favorite is the first option. While the last option (no thumb) works well to keep the hand in place, I find that involving the thumb allows faster speeds. I prefer the second pattern.
Once you’ve determined which patterns feel right to your hand, work them up and then work on mastering them back to back with the other patterns.
Pattern 1 + 2
Pattern 1 + 3
Hope this helps!
