Twelve Etudes for Children (No.10 Cockroach Toccata)

Etude No.10 stands as one of the most challenging pieces in this collection. The piece is inherently atonal, with its tonal center on A, but its concept deviates entirely from tonal music. Playing this piece demand not only finger strength but also engagement of the palms, wrists, arms, shoulders, and even the entire body. Precise control of muscles in each part is essential to perform this piece perfectly.
The title "Cockroach Toccata" vividly describes the emotions when encountering a cockroach and the various ways we attempt to get rid of it.
