Ice Age How to Destroy Angels Tuning: Drop Bb and/or Drop D NOTES (READ BEFOREHAND): I tabbed this in two tunings for this piece. Drop Bb (Bb, F, Bb, Eb, G, C) and a Drop D (DADGBE) for those people who don�??t want to tune down. And it�??s basically all palm-muted (and most likely finger picked) unless said otherwise. This is in two parts. The lowest Bb (or D) string is the rhythm, while the rest are the melody. Also, there�??s a lot going more going on in this song, so this is just the skele (azchords.com)
