Substantial contributions to flute literature of the twentieth century were made by the Dutch composers Willem Pijper (1894-1947) and Henk Badings (b. 1907) in the Sonata per Flauto e Pianoforte (1925) and the Concerto for Flute and Wind Symphony Orchestra (1963), respectively. This paper is an examination of the compositional devices employed by Pijper and Badings in these two selected works, with a discussion of the elements of form, tonal language, rhythm, motivic usage, orchestration, and innovative flute techniques. Emphasis on Pijper as teacher and mentor to a generation of Dutch composers, including Badings, gives the basis for a comparison of the Sonata and the Concerto.
