Hi I am a 56 year old medical doctor -if you at 37 years are 'old' I hate to think what I am.
I have written an app for iphone/ipad just for someone asking your question!
The app allows you to play classical piano pieces (limited to this because of copyright with more modern music).
It provides a way for you to choose the level of control you want to have as you play.
The idea is incredibly simple- the device/program looks after playing the right notes in the right order. You have control about when the notes start/stop and exactly how loud/soft they are.These are the elements that give expression to any piece of music. You play the piece of music from the touch screen and do not need to read music. The app gives a representation of the timing for playing the notes which is simple and intuitive.
I plan to release the app on the Apple app store soon but am looking to try and find how much interest there might be for the app.
All the best
