Registry of Guitar Tutors – this is another examination body, specifically for guitar and ukulele exams.
IMSLP Website – home of the Petrucci Music Library, where you can find printed and recorded music that has entered the public domain (i.e. it’s free to share and copy).

Composers on Classic FM – great source of info on many Classical composers.
AQA Past Papers – if you’re studying GCSE music with the AQA exam board, this is a valuable resource.
MuseScore Sheet Music – MuseScore is a very handy piece of free music notation software. I use it to write out music for myself and my pupils, and there’s a wealth of scores available online by others.
PianoEscort – on this YouTube channel, there are a number of accompaniments for cello pieces (and other instruments).
Andertons Music Store – based in Guildford (and online) this is my music store of choice, though it’s worth mentioning that other music stores are available!
