Help me to validate my piano startup idea!

Dear community!

If anyone ever searched for the notes sheets on the marketplaces, I have an idea how to improve the experience by dynamically changing the difficulty of some parts for the written sheet Here's the link to a screenshot of the quick prototype https://ibb.co/F8G7RQt

I'm imagining my program will be able to configure at least 3 parts: melody line, bassline, and rhythm. This way you can simplify notes if you are a beginner or make them sound more sophisticated.

I would like to hear your thoughts! How useful this feature can be for you? And have you ever had troubles with finding sheets suitable for your playing level? 

Not for me, slightly predating the 'instant gratification' age. Is there a point in bypassing the chore of practice? I'm a casual pianist. In pre-lockdown days I'd play (lounge style) at receptions, weddings and things. While learning, my teacher spent much time on analysis (working out how something should be played) and exercises away from the keyboard. As he said, he wasn't there just to supervise practice. Anyway, my spiritual teacher was Liszt and I studied a couple of his pieces to learn a) fast arpeggii, b) to play a tune spread between the thumbs of both hands and c) to bring some kind of art to my playing. 

I can't see how these things can be simplified. Can your program detect a melody 'in the middle'?

If only people would do a bit of analysis and practice sensibly they'd find they could play things way above their paygrade.

However, all told, your effort is meritable if it works and there are no doubt people who'd love to 'fake it' a bit.
