Pieter van der Staak (born in The Hague, May 25, 1930 - passed away November 2, 2007 in Zwolle), Dutch classical guitarist, composer and professor of music. He has composed a large number of chamber music, among which are works for string quartet, clarinet quintet and cello trio. He has written many didactic pieces for one up to four guitars because he felt involved with the development of new didactical material. Besides compositions for cello ensemble and accordion orchestra, he composed music for less common combinations such as guitar, flute and clarinet. He wrote many works for guitar teaching, published by Ars Nova (Sweden), Hortensia (Paris), Suvini Zerboni (Milano) and Broekmans & Van Poppel (Amsterdam). Concertino III, for solo guitar and guitar quartet (1970) is published by Donemus. Recently the Canadian publishing house Les Productions d'OZ issued several unknown works composed by Pieter van der Staak. (Hide extended text)...(Read all) Source : Wikipedia
