This paper reports on the second stage of an international study exploring the future of secondary school music education. Within a discursive context that tends to regard music education as failing to meet the needs of many students, we instigated a three-step Delphi study to capture views from educators across the English-speaking world. Interviews with leading music education researchers reported on in our first paper [McPhail, G., and J. McNeill. 2019. "One Direction: A Future for Secondary School Music Education?" "Music Education Research," 21 (4): 359-370.] identified a disconnect between how music education is currently realised in secondary school and how these researchers thought it should be taught. The findings from this expert panel were used to seed a two-round Delphi study where a wider international panel explored strategic issues facing the sector. In this paper, we report on the data generated from the first of these two wider Delphi rounds. Four areas were identified where gaps exist between actual and desirable classroom music teaching: the core purpose of music education, curricula content, curricular delivery, and context. Although panellists reached consensus on many issues, they held markedly different positions on others. These findings provide an agenda for exploration and reflection by researchers and practitioners, and raise the question -- is there a single desirable direction for twenty-first century secondary school music education?
