Tuba Quartet (Neuheit Tuba) Composer, music theorist and harpsichordist Yngve Jan Trede (1933–2010) was born near Hannover, Germany. In 1947 he met with writer and organ theorist Hans Henny Jahnn, who knew Trede’s family and later became his parent-in-law. Young Trede received education at the Staatliche Hochschule für Musik Freiburg and in 1960 he completed his diploma in piano, orchestral conducting, music theory and composition as principal subject at the Staatliche Hochschule für Musik in Hamburg. From 1958–1966 he taught at the same institution and in 1968 he was appointed associate professor at the Royal Danish Academy of Music and later (1973–1995) as professor in music theory and composition. At that time, Yngve Jan Trede had plans to gain his Danish citizenship, as he had greatly influenced and impacted the Danish music environment as a fine harpsichordist and a highly respected music theorist. As an active composer, Trede’s extensive list of compositions include works for various solo instruments (organ, marimba, harpsichord, piano), chamber ensemble, orchestra and song cycles. In 1978 he composed an opera based on Hieronymus Justesen Ranch’s comedy ‘Karrig Nidding’. It received the title Det nærige svin, but was performed under a different title (Danefæ) in 1980 at the Royal Danish Theatre. Yngve Jan Trede also used his background as a music theorist, composer and skilled musician to complete his edition of the final movement of J. S. Bach’s great work Die kunst der Fuge in the 1990’s. by Claus Røllum-Larsen. The Royal Library
