100 Short Studies for Great Flute Playing by Rien de Reede
In this book you will find melodies and well-loved themes as well as short exercises and dances. A number of canons for three and four flutes, useful and stimulating in group lessons, are also included. Although later in the book C1 is introduced, the compass of the pieces never exceeds D1 to E3, while the earlier pages focus mainly on a tessitura of G1 to D3. The keys employed more-or-less equally are C Major, a minor, G Major, e minor, D Major, b minor, A Major, F# Major, F Major, d minor, Bb Major, G Major, Eb Major, and c minor.
