Sir, - Anne Byrne's piece about Junior Certificate Music (June 18th) is full of curious items, such as a Ms O'Connell's idea that one can get to certificate standard without having heard of a semiquaver. But never in 82 years have I heard of a metronome being in any key, let alone a different one. Would someone please explain? - Yours, etc.,
(your former music critic),
