I play the guitar. I picked up a Stella acoustic guitar that my folks had around the house when I was 11 or 12 and taught myself to play. I played in a few bands, set it down when I discovered computers, and I didn't touch a guitar again for years. A couple years ago I wanted to start playing again so I went to a store and picked up a Martin acoustic guitar. (My 12 year old self was thrilled for me.)
The other day I was playing something I play and I thought, "hmm, I'd like to hear this with a haromonized part lower on the neck. How do I make that happen?" So I figured out how to record myself playing, learned enough Garage Band to combine the tracks, and put this little song together. It's rough but it was a fun process and it was great to hear those harmonies.
