Tunings: D standard

D Tuning, also called One Step Lower, Whole Step Down, or D Standard, is an alternate tuning for Guitar. Each string is lowered by a whole tone or two semitones resulting in D-G-C-F-A-D It is used mostly by heavy metal bands to achieve a muddy sound and by blues guitarists, who use it to accommodate string bending. Chuck Schuldiner was known to use this tuning exclusively, stating that "You gain some low without losing control. By tuning lower you start to sound like the rest. I also refuse buying a 7-string guitar, it's a trend, nobody is being creative with the extra string, they only use it for an extra low tuning".[1] Kreator was another heavy metal band that used the D tuning a lot throughout their career. So was Obituary. Kurt Cobain used this tuning in his guitar to perform in some songs from the Nirvana's Nevermind, like "Come As You Are". Mastodon also commonly use this tuning,[2] as have Nightwish since the Century Child album.
