A deliberate practice app for guitar players who want to level up

This looks super cool, and very similar to a need I have, except I'm not learning the guitar.

I'm learning my first (serious) instrument and I've decided on the lyre, since it's similar to other string instruments (guitar, ukulele, traditional harp) but a bit easier.

Will you support other instruments for lessons, other than the guitar?

I am going through the alphatex documentation in more detail and chances are that any stringed instrument could already be supported. Checkout the tuning section - https://alphatab.net/docs/alphatex/metadata#tuning.

It might even work for piano as well, there's an example here - https://alphatab.net/docs/alphatex/notes/#multiple-voices

Awesome!

I'd think about considering a more common instrument because you'll have a bigger support network.

You can find guitar teachers literally anywhere, guitar tabs are all over the internet, and you probably have friends who can give you a few pointers if you get stuck. Ukelele and bass guitar aren't that far behind.

When I was in college, in 1996, several computer science professors told me I was playing with toys and no serious organization would use Linux as an operating system.

In 1997, I asked a math professor about a statistics program, and he said R would never be used for real work.

In 1998, I was told that sure, I could learn Python if I wanted, but I should learn Java, but if I insisted on a scripting language, I should stick with Perl.

I don't use tools because I think they're popular, I do what I enjoy.

Also you didn't ask me why it might be easier for me to learn the lyre, which has to do with physical limitations I have.
