My daughter is only in Year 7, but adamant she wants to do a GCSE in music (although she's always been interested in doing something arty/design). At the moment she plays a violin, but wants to play another instrument. She's interested in flute, guitar and piano, but think she'd play anything suggested. Happy for her to do it just for fun, but in case it takes her anywhere workwise, which other instrument would be good to choose?
