Guitar - Level 3 - Digital Download SKU: A0.1014600 By Billie Eilish. By Billie Eilish O'Connell, Billie O Connell, Finneas O Connell, and Finneas O'Connell. Arranged by Sebastian Albreht. Pop. Guitar Tab. 6 pages. Sebastian Albrecht #5728671. Published by Sebastian Albrecht (A0.1014600). Bad Guy for Solo guitar consists of a regular music score with an added guitar tab. The arrangement is in the original key and with full original tonal content as well, which makes it a bit more technically damanding, but I have included many fingering ideas to ease your path towards playing it successfully.If you need a simpler version of this song, or without a guitar tab please contact me through SMP or sebastian.albreht@gmail.com, and I will post it on SMP.
