In recent years, music education has seen a decline in the number of students choosing to continue their studies at Key Stage 4 (14- to 16-year-old students) and choose music as a GCSE option in England. Whilst the English Baccalaureate (EBacc), a school performance measure which excludes the arts, has come under much scrutiny as to its impact on school music, enjoyment and the perceived importance of music lessons could also be contributing factors to low uptake. This paper presents student survey findings from the first part of a two-phase project that was based on a qualitatively driven mixed-method research design. Findings demonstrated that a decline in enjoyment and in the importance attributed to school music occurred in the first three years of lower secondary school (Key Stage 3). The enjoyment of school music was linked with the students' engagement with practical components of music making, and its importance was mostly equated with future employment opportunities. The findings are discussed in terms of their practical implications in the teaching of music in secondary schools.
