These studies focus on transposition. Italian composer Reginaldo Caffarelli created these 100 exercises of varying lengths in written C major (or A minor) and indicates to which key each is to be transposed. A sample C major (or A minor) scale, and the scale of the transposition key, is printed at the beginning of that group of exercises. A series of arpeggio exercises are included to develop comfort in a variety of keys. The end of the book contains extended etudes in which the transposition requirements change throughout each piece several times.
