This interests me, because I have a continuous internal debate about whether I should be memorising pieces or not. I have my own arrangements of European folk tunes fairly well committed to memory, but I have not attempted to memorise classical pieces which are often longer, more complicated and with fewer repeated phrases. From what others say here, I am starting to feel that for my playing to ever be of a good enough standard to play in front of others, I should work on memorising, so that I can really start to focus on playing musically, rather than just striving to accurately play the notes from the printed page. So I'd like to ask a follow up question. How many pieces do people find they are able to memorise effectively? I realise this is a slightly obtuse question, as pieces vary in length and complexity and we're all different, but I would be interested to know, in general terms. I suppose things that have been memorised can be forgotten if not revisited, but then, hopefully, the re-memorisation process would not take as long as from scratch. Anyway, I would be interested to hear thoughts on 'memory capacity' as it were, and I shall commence the memorisation of a piece when I practise later!
