Piano Technique: Intermediate Level Finger Exercises, Vol. I, begins with exercises in patterns of two, three, four, and five notes, from the interval of a second to the octave, with all possible fingerings, and continues with broken thirds, sixths, and octaves. Later chapters provide training for passing the thumb under the hand, double-note thirds, sixths, and octaves, extensions, and scales, arpeggios, chords, broken chords, octaves, and broken octaves.
The intermediate book clearly shows the basic design of all of the books, and, as such, provides excellent preparation for its later companion volumes, the virtuoso and advanced books. All of these books can be used together as part of a coordinated practice regimen. This is a unique and original approach for developing piano technique.
