Here's an idea for a 16-bar blues form... just two tracks: 1) beatboxed "live click" track, 2) 5-string electric bass guitar track (tuned EADGC)... I doubled the bass track during the mixdown, and added some tremolo to the duplicate, and a slight phase shift too. highpass filter and some light compression was also used on the bass. no metronome, quantization, looping, time-warping, stretching, chopping, or other editing. tracks were recorded onto SD card using a Zoom R16 digital 8-track, and mixed using Audacity.
