i have found instant piano genius very helpful to me as i find trying to read music and play at the same time very frustrating, bearing in mind that i am a mature learner . Tims way of explaining music is by far to me the best way after all we do listen to music with our ears, but you have to put the practice in, you will only get out what you put in. I only wish instantpianogenius was around a few years ago. Thanks for your help Tim .. Best wishes Alex Denning
