BZla Bart-k's Mikrokosmos is a collection of 153 pieces for piano designed by the composer as a series graded according to difficulty. The pieces were written between 1926 and 1939, and have become by far the best-known series of teaching pieces by a major composer in the twentieth century. This in-depth study investigates Bart-k's Mikrokosmos from three main viewpoints: the genesis of the pieces, their pedagogical value, and their stylistic qualities. The book is intended for piano teachers, students, and performers as well as anyone interested in Bart-k's life and work as pianist, educator, and composer.
