Each month, Gramophone's online quiz asks you to draw on your musical knowledge – and your skill at using a search engine (or, if you prefer, you are very welcome to reach over to your book collection!) – to solve a series of questions. Some answers you may get very quickly, others will be somewhat more cryptic – but all correct entries will be entered into a draw to win an Evoke-2S digital radio from Pure every month. The deadline for the latest quiz is February 23. Good luck!
