It’s just a matter of some education. Because it’s really just another skill that can be learned like any other. No different than learning how to make a good omelette or pilot a space shuttle. You’re not born knowing how to do it. You have to learn, either by instruction or through trial and error. It’s all a matter of gathering the needed resources for learning what you want to learn and (ideally) finding a teacher to help you along. Having a qualified teacher - whose teaching style works for your personal learning style - is the single best way to smooth and shorten your learning path.
Can you learn it at 30? I’ll be 67 next month. In the last two years I’ve learned basic French, and got heavily into synthesizers on a technical level. Just recently I decided I wanted to learn about, and how to play, Metal style bass. I’m working on that as we speak. And I’m seriously contemplating finally picking up and learning to play the saxaphone, which is something I’ve been thinking about for the last 40 years. (I’ve played every family of instrument but reeds so far. Horrors! There’s a gap in my musical experience!!!

) Figured it’s now or never considering my age.
So is 30 too late?
You tell me. In my case, as long as I’m still breathing I figure any time is a good time to learn something new. I’m always looking to acquire new skills and knowledge.
But that’s me. What about you?
