How long does it take to learn the basics, and reading notes, and things like that? And if you play piano how long did it take you?
It all depends on you, and how much you practice. For some it takes longer then others. For me it took about a year before I could read music and play some classical pieces like Mozart, but for some people it can take 3-4 years. It’s different for everyone, but I’d say a good estimate is 2 years
