If you don't practice for three days, everyone will notice." It's something you have to really maintain. So unfortunately, I don't play it that often but I may take it up again. If you don't play for a while, you just can't hit the notes. It's like going to the gym. If you go and do weights, you can lift x amount of weight and if you don't go for ages, you've gotta start again and start from the beginning. So it's a bit like that. It's just a muscle.
