As gleaned from New Music of the Nordic Countries (by John White, Jean Christensen, Kimmo Korhonen), Mogens Christensen is a Danish composer who studied composition at the Royal Academy of Music with Ib Nørholm.
Christensen has also studied with Per Nørgârd, Karl Aage Rasmussen, Poul Ruders and Hans Abrahamsen at the Academy in Århus.
Of recorder interest is his A Fancyer's Delight , a concerto for recorders played by one soloist and a mixed ensemble. It uses tunes from a book (1717) of melodies that were taught to domestic birds, together with quotes from music of other composers who have referred to birds ( William Byrd, Antonio Vivaldi, Respighi, and, of course, Igor Stravinsky and Messiaen).
It is a capstone work in a series of compositions for recorders.
