This Synthesia's great fun. It's all about dexterity, for now, I'm thinking - just keep getting more accurate on increasingly difficult bits of music: which might take a year to get to any kind of breakthrough.
Not to lose sight of notation, I'll investigate Noteflight when I've a bit of time. There's also Sheet Music Editor. Haven't looked at apps for the iPad yet. Initially, I want to note up the simple bits that I'm practising on, and blog them if possible.
Meanwhile, as a lifelong Guardianista and keyboard student, I couldn't resist shelling out at Waterstones (Amazon? Amazon? Who the fuck are Amazon?) for the Alan Rusbridger book. Be good to have a shot at Chopin's Ballade one day. Though my personal goal is more modest, it still looks bloody difficult: Maple Leaf Rag. Two to three years, maybe?
