The man who as W. D. Munn published papers on that branch of mathematics known as semigroup theory had another side to his personality: Douglas Munn (1929–2008), professor of mathematics at the University of Stirling, was also a fine pianist and a gifted composer. His piano music has its origins in Chopin, Brahms and Bartók but is clearly also inflected by Scottish folksong – much of it has a sense of the hills and the open spaces – and is written by someone with an intimate knowledge of the instrument. The Latvian pianist Arta Arnicane knew Douglas Munn and this album is the fulfillment of an unspoken promise to record his piano music.
