I’ve been a purely aspirational musician for decades. I was given an acoustic guitar at 20 and never used it. I bought an electric guitar at 30, thought it was broken, and stuck it in the closet. At 38 I realized it was a floating bridge guitar, stuck a USB stick behind the bridge, and played a couple hundred hours of Rocksmith, which teaches you almost nothing of importance, but at least it makes your fingers a bit more nimble. I plan to take actual 1-on-1 lessons this year, but am generally pessimistic about my own ability to improve at any task, regardless of effort.
On the other hand, I’ve been told I sing well, and I learned the words to MGMT’s Brian Eno this week after listening to it on a loop for north of 16 hours. So, I can be taught.
