This paper overviews the decline and revival of music education in New South Wales schools from 1920 to 1956. Commencing with a focus on vocal music during the period up to 1932, a time of decline in music teaching, the paper examines initiatives introduced in 1933 to address shortcomings in music education, and the subsequent changes in curriculum and teaching during the 1930s. Evidence of a variable revival lies in the school choral music movement of 1939 to 1956, and in how music education diversified beyond its vocal heritage from the late 1930s and early 1940s, with new emphasis on music appreciation, percussion, flutes, and recorders. By the mid 1950s, involvement in, and quality of, school instrumental music was continuously improving.
