The practice of études is invaluable for the development of a student’s technique. However, it is sometimes difficult to achieve good intonation without another instrument providing a tonal frame of reference. These accompaniments were composed to solve this problem.

To achieve this goal, they are written in a tonal style, sometimes as simple accompaniments, sometimes as melodic pieces which force students to listen more carefully and support a part other than their own. All can be played by intermediate pianists so that even an amateur can take part in the practice sessions.

If no pianist is available, these accompaniments have been recorded and are available for purchase. To make the recorded tracks easier to follow, an introduction—usually two measures—precedes each étude.
