I play trombone, a bit of guitar, and I'm learning piano. I feel like messing around on the guitar when I was little helped with the idea of music in general, but I don't have enough skill on anything to really use it (however I'm learning piano for the sole reason of playing for my own songs)
That's awesome. Good luck on your piano lessons! As an amateur pianist myself, I can definitely say it's helped me gain a deeper understanding and appreciation of music in general. Thanks for the answers!
