Merry Christmas by Darth Fender I chose this beautiful piece of music, in the version by Pentatonix.
I used their videos to catch all the vocal parts, and arranged them for guitar.
All the sounds you’re hearing were obtained with guitars (and a bass), no other instruments were added in post production.
The only parts you’re not seeing in the video are some guitar fills that happen in a couple of points during the songs (too little to have a sense in the video) and the “charleston” sound that was recorded separately using the acoustic guitar
