Short note written from Harvard, where Piston was an influential teacher from 1926 to 1960. He writes to the violinist Boris Koutzen commenting on a recording, presumably of Piston's music, and saying he had no performance suggestions. He compliments him on the quality of his student group and sends his congratulations to them and to the organist, Donald Pearson.

Piston must be referring to either his Partita for Violin, Viola and Organ (1942) or his Prelude and Allegro for Organ and Strings (1943).
