The GCSE music examination is the principal form of accredited study for students aged 15+. (More students take the examination than previously took GCE O-level and CSE examinations combined.) For this reason the examination is generally thought of as a success. An analysis is made of uptake rates during the period 1994-8 and comparisons are made with uptake rates in other optional subjects. Based on this evidence, a suggestion is made that GCSE music is not as successful or attractive to students as is commonly thought. An assumption is made that there are factors that make this situation surprising and worth further research. Some possible reasons for the current situation are explored.
