11 Sonatinas, Opp. 151, 168 by Anton Diabelli (1781-1858). Edited by Willard A. Palmer. For Piano. Masterworks; Piano Collection. Alfred Masterwork Edition. Form: Sonatina. Classical; Masterwork; Romantic. Intermediate; Late Intermediate. Book. 88 pages. Published by Alfred Music (AP.2419).
The Four Sonatinas Op. 151 and Seven Sonatinas Op. 168 have proved to be the most enduring of Diabelli's compositions because of their importance as study material for pianists in the intermediate grades. Approximately the same difficulty as Clementi's famous Six Sonatinas, Op. 36.
