arty - glad I'm not the only one struggling to get back into music! I've got a teacher, and I do jazz mainly (incidentally, playing the right notes in the wrong order is a form of jazz, or so I keep telling myself...)
I'm just doing random things really - no exams - too old for that - but i would like one day to teach, so I need to prove myself as a player first. As it's jazz, there's lots of improvisation, so the world is your lobster.
Otherwise, I've done a bit of Chopin, and I'm doing a really fast Beethoven piece, which is a sonata finale. Presumably you're doing Grade 3 ABRSM? What tunes?
