This is the second woodwind quartet arrangement that John Pratt has created from Haydn’s late piano trios. The Piano Trio in A major, Hob. XV:18, adapts nicely to wind instruments, especially after transposition to the key of B-flat major. The arrangement is scored for flute, oboe, B-flat clarinet, and bassoon; click the link to preview a page of the score and listen to an audio sample.
