 The " Scottish " Period began in the early 1930s where all his works were tinged with a remarkable Scottish nationalistic colouring , indicating most persuasively the ambitions of the composer like contemporary Béla Bartók , to nourish his style on the music of his ancestors and countrymen . Chisholm 's Sonatine Ecossaise , 4 Elegies , Scottish Airs , and Piano Concerto no . 1 " Piobaireachd " display a style of percussive bite and energy which made much use of dissonances , note clusters and pounding rhythms in the " Bartók manner " along with material derived from Scottish Folksong and rhythmic dance figurations . His style is so similar that Chisholm 's critics have repeatedly referred to Chisholm as " MacBartók " .
