Waltz Etude was composed by William Gillock as part of his twentieth-century pedagogical piano repertoire, which sought to combine technical development with vivid musical character. Gillock believed that student pieces should sound like real music, encouraging imagination, stylistic awareness, and expressive playing from an early stage. This work blends the traditional waltz idiom with étude-like technical focus. While pedagogical in intent, it emphasizes musicality, rhythmic stability, and tonal balance rather than mechanical repetition, reflecting Gillock’s distinctive contribution to modern piano education.
