As I waited for my left hand to heal from surgery, I took the opportunity to explore the very limited literature for the right hand alone. There has been very little ever written for just the right hand at the piano. However I did find one interesting nugget. Charles Alkan wrote a series of Etudes in his Op. 76. The first one is for the left hand, the second is for the right hand, and the final is for the hands reunited. These are substantial works with the Right Hand Etude running about 24 pages. It is written in a theme and variation format. It has the expected Alkan challenges but sits very well in the hand.
For therapeutic purposes I have returned to playing the 15 Two Part Inventions of Bach. One of the most interesting editions of these and the Three Part Sinfonias is the Alfred Edition with Willard Palmer as the editor. As part of the preface of each set, Mr. Palmer produces a chart of about 15 different performances, editions, and commentaries’ tempos. For most of the works there is about a 100% difference between the fastest and slowest tempos. As an initial part of my rehabilitation I am exploring how to create effective interpretations at the slower tempos. As my hand improves I will move to the other side of the scale and explore the changes which occur in the character of these pieces as their tempos increase.
One aspect of much of Bach’s music which has always fascinated me has been the flexibility of his music to make sense at a wide variety of tempos. There is content within every note such that even pieces which are traditionally played very fast such as the 4th invention in d minor can be played quite expressively at a slow tempo as well.
