Idk if it is actually gonna work, I'll only know that after I try it. But right now, I notice that one of my biggest bottlenecks in reading music, is that, whenever there is a note that is quite a bit away from the clef, or other notes I played before, it takes me some time to recognize what note it is. Right now I am planning to make an app that shows me notes, I'll have to press that key as quickly as possible, and then the next note pops up. I then plan to have a bit of an anki type thing going on, where, if you get a note or chord right, and within a short amount of time, it takes longer for that same note or chord to show up again.

I am not expecting this to be a silver bullet for sightreading. There is still gonna have to be a lot of actual music reading involved, but it is the goal for this to eliminate a bottleneck and give me a bit of a head start. I just want to do more playing and less searching for now.

One thing I've been looking for is instructional software that shows the staff with notes on it and illuminates the notes you're ACTUALLY playing instead of just the ones you're supposed to be playing.

I don't know why this seems to be rare; isn't it the obvious thing to do?
