Under the influence of his friendship with Bartók, which led to his becoming known as McBartók, Chisholm has demonstrated that Scottish folk-song is as fruitful a source for art music as have been those of Poland and Hungary; Chisholm's Scottish Airs are good equivalents to Bartók's better known Improvisations on Hungarian Peasant Songs; his sonatinas are delightfully inventive, and his early music is always well crafted.
