I'm in a tricky position. I've been playing guitar for around ten years and am fairly good at improvising and tinkering around on a piano, too. I understand sheet music, I can decipher it, but I can't sight read it. I'm aiming to change that.
The issue I'm finding is that I'm really good at transcription, and as such if I'm playing a piece I already know, I generally find that I've worked out the next part before I've read the sheet music.
Even if it's something I don't know that well, after a half-dozen times practising a part, I'll find that I've memorised it, and as such am not looking at the notation but using my ear to determine where I'm going next.
I'm trying to overcome this situation, but I'm struggling to think of a proper way to do it. I'm perfectly capable of sight reading guitar tablature, and I'd love to get to a similar position with the piano, but I'm finding that my memory is being somewhat arrogant, and causing me to rely on it and my ear, rather than reading the notation until it becomes second nature and I'm more able to sight read it.
