New fan from Colombia South America. Luckily I discovered you last night. I'm an engineer stdnt but today I started a music production class. It's a MUST to learn to play the piano for success?.Thanks
The keyboard provides the best visual model for music theory, so if you're going to be composing, you should at least learn the basics. It can also help you understand frequency ranges for EQ. Still, plenty of successful producers don't know the first thing about theory, and can't play an instrument (other than their laptop!).
