Love your thinking here, and your landing page is fantastic. Very inspiring. The 'before' and 'after' toggling is a very effective way to illustrate the value your system brings.

If you can help my mom put an Ipad on the music stand instead of a song book she has to manually flip through while playing you might just win another customer. Right now, when i do a jam session with her (I play guitar) she literally has to stop playing piano to flip the pages. She does this 3-4 times a song which is quite jarring. The humble paper song book and conventional notation system could use a 'shaking up', and you guys have started innovating this problem, so thanks!

I could easily see this becoming the tabulation (tabs) system for that piano and other instruments have not had to date.

Well done!
