Poll: Which name to use for a piano teaching application?

A bunch of people, myself included are working on a program that will help people to learn how to sightread and play the piano/synth/organ. It is meant to help people improve their skills no matter how good (or bad) they already are, the basic idea is to show them a score, help with sightreading and to train by playing, improving multiple skills at the same time.

The project is progressing quite nicely, we have a small group of beta testers who have given us lots of useful feedback the bulk of which has been incorporated. The program is approaching the MVP stage, but one major thing we don't have yet is a really good name for the project, below is a list of candidates, and I would very much appreciate it if you could vote for your preferred name and maybe (if you want) explain why you think a particular name is good or bad.

This project is a direct result of the COVDI-19 epidemic, I figured with more time on my hands than usual I should at least learn a skill and picked learning the piano. I found that the software that I was using had substantial limitations and so I asked my colleagues for help and feedback and we ended up building our own. Naming it is a hard though, hence this poll (you can vote for more than one name if you want).

If you want to have a look at the beta application drop me a line (jacques@modularcompany.com), and if you voted in the poll, thank you very much.
