However over time it becomes easier and easier - and then you wonder is sheet music somehow optimal or is it 'good enough' and has withstood the test of time (also accounting for the fact that there is an enormous corpus of existing sheet music).
The question regarding this app (which looks awesome) is, is this format for reading music better than sheet music at the expert level (for professional musicians). And if not, how can we get that 10x improvement to make the switch from sheet music to something better.
