Willi Apel

Willi Apel (10 October 1893 – 14 March 1988) was a German-American musicologist and noted author of a number of books devoted to music.

In 1950 Apel's interest in early polyphonic notation resulted in an important edition, French Secular Music of the Late Fourteenth Century.

Over the years, CEKM presented the music of less known composers such as Johann Ulrich Steigleder, Bernardo Storace, Peeter Cornet, and others, and also included modern editions of various important manuscripts such as the 16th century Jan z Lublina tablature.

Apel was the general editor for CEKM and edited a total of ten volumes; his pupils provided dozens more.

1967 saw the publication of Geschichte der Orgel- und Klaviermusik, a large work on the history of keyboard music.
