Ulrich Leyendecker (29 January 1946 — 29 November 2018) was a German composer of classical music.
Leyendecker studied composition with Ingo Schmitt (1962–1965) and Rudolf Petzold (1965–1970), and piano with Günter Ludwig.
In 1994, he became Professor of Composition at the State Hochschule for Music and the Performing Arts of Heidelberg-Mannheim.
He employed regular time signatures in his pieces, but it sometimes does not sound that way, for he utilized carefully calculated and complex rhythms.
His music often contains novel sonic architectures, while still managing to express powerful emotions directly to the listener.
