Also still in manuscript are the "24 Toccatas and Capriccios". Another contemporary composer who has written many toccatas is Emma Lou Diemer. His "toccatas" could be used in masses and liturgical occasions. As a composer Reutter is best known for his collection of toccatas. Frequent use of 12/8 gigue-like endings is similar to Froberger's toccatas. Piccinini concentrated on toccatas, courantes and galliards, as well as different kinds of variations. Other composers of well-known toccatas include Maurice Ravel, Dmitri Kabalevsky and Aram Khachaturian. Kaikhosru Shapurji Sorabji wrote four toccatas for solo piano, while Moises Moleiro wrote two. Among his most-used forms are three-part adagio slow movements, fugues, variations and toccatas. Storace's two toccatas are rather brief pieces, less complex harmonically than their Italian predecessors. The toccatas represent Bach's earliest keyboard compositions known under a collective title. Furthermore, no other Baroque composer used pedal point with such consistency in toccatas. Like Bach's other clavier works, these toccatas are frequently performed on the piano. Beyond the Baroque period, toccatas are found less frequently.
