I consider myself ‘unable’ to ‘play’ the guitar, whatever that means, but it doesn’t stop me from messing around with one occasionally. Here’s something I did earlier while waiting for a pizza to cook.
It’s three overlaid tracks, unedited and with no thought given to alignment (other than making sure they all start at the same time):
#1: prepared guitar: a toothpick threaded between the strings, and flicked occasionally. Reverb added afterwards.
#2 & #3 are played straight and unplanned, the result of just arbitrarily putting my fingers in different places.
Technical note: there is some horrendous DC offset on the reverb, so be prepared for a slight pop if you stop listening part-way through.
