One of the easiest ways to improve right-hand arpeggio studies like Heitor Villa-Lobos’s Etude Nº1, Leo Brouwer’s Etude Nº6, or Francisco Tárrega’s Estudio Brillante, or the parts of pieces where arpeggios occur for an extended time is understanding when exactly the left-hand fingers must place or release to prepare for the next note or chord formation. Often, fingers are placed too early or too late, and both situations either overexert the fingers, the nerves, or worst of all, the musical intent. Arpeggios are, after all, broken chords. It is very rare that all fingers should place at once if they come in ‘broken’.
Sequential planting of the left-hand fingers is a skill that choreographs left hand movement to a deeper and more subtle level than simply grabbing at the next chord frantically at the start of a measure.
Here is a simple but effective exercise to help develop the principle of timely left-hand finger placement. The key is to time the placement of the new finger in relation to the meter and when it is due to enter and to avoid arbitrarily placing it at the beginning of the measure.
Go through each exercise a few times plucking every single note of the arpeggio. Once this feels comfortable and the timing is starting to feel synced with both hands, slur the entering note in time to develop a sense of pulse in the left hand, too.
There are infinite ways to expand this concept but one of my favorites is to move into cross-rhythms with accents. My idea of fun!
