24 Studies for the Left Hand, Opus 718
Czerny's Op. 718 is a set of 24 studies that emphasize training of the left hand. The work is not a collection of left-hand solo studies as one might guess from the title, though it focuses on the dexterity of the left hand. The studies include the following types of technique: scales, double thirds, full (four-note) chords, arpeggios, skips, melody and accompaniment in the left-hand part, and many others.
