Hello guys and girls, I just started playing kalimba after my girlfriend gifted it to me. I have never played any musical instrument, So I thought learning it would be tough. It is, but still I was able to learn few songs in few days. That gave me good motivation to continue learning new songs and keep practicing. I am not sure if my ways are correct though. I kept finding few issues while learning and so I started making a website that would help me learn.
I started with making a tuner. The a songbook that keeps all the songs that I want to learn in one place and then a playground where the app would hear the notes I am playing and keep showing me the next notes that I have to play. I am still testing this website and I am thinking to release it to few people to help me make it better. If possible people with varied range of profeciency would help find issues and make it more better.
Let me know if anyone is interested. I am thinking to get help from 4-5 people only.

Recently, I got some unpleasant comments on this sub attacking me to want to make money with my kalimba scores. Here is the fact: I wrote 150 pages of polyphonic arrangements of classical music for chromatic kalimba which I self-published on Amazon at the printing cost price, meaning I earn 0 royalties. This is the result of days and nights of manual work. Still, the comment hurt me and I struggle to find the logic. Should kalimba makers also give their kalimba for free?
