I had also posted on the "What are you working on?" thread yesterday - https://news.ycombinator.com/item?id=43531684.
Happy to answer any questions.
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?
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.
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.
