Ulrich Leyendecker was mainly interested in symphonies, concertos, chamber, and instrumental music.
He studied composition with Ingo Schmitt (1962–1965) and Rudolf Petzold (1965–1970), and piano with Günter Ludwig.
During 1971 Ulrich Leyendecker became a lecturer at the Hamburg Academy for Music and Performing Arts, and in 1976 he was appointed Professor of Composition and Theory at the Hamburg Music and Theatre Hochschule.
Leyendecker became Professor of Composition at the State Hochschule for Music and the Performing Arts of Heidelberg-Mannheim, in 1994.
His music, although not serial, is largely atonal, but often with subtle hints of tonality.
Ulrich Leyendecker employed regular time signatures in his pieces, but it sometimes does not sound that way, for he utilized carefully calculated and complex rhythms.
Leyendecker’s music often contains novel sonic architectures, while still managing to express powerful emotions directly to the listener.
Leyendecker mostly employed classical abstract forms such as the symphony and concerto form while avoiding operas and ballets.
Ulrich Leyendecker passed away at 72 years old.
