Kalevi Aho: Quasi una fantasia for horn and organ

Quasi una fantasia for horn and organ (2011) was composed on the commission by organist Jan Lehtola, who premiered it with horn player Petri Komulainen in 2012. The piece is extremely virtuosic, and almost concerto-like in nature. At times the horn plays also quarter-tone scales by combining ‘perfect’ and ‘imperfect’ (the 7th, 11th and 13th) overtones of different harmonic series together. Duration 16 minutes. Buy now
