“Heavy metal and drop D is a match made in heaven”: Eddie Van Halen used it, Jimmy Page loved it, and all of your heavy metal heroes have tried it – drop D made drop-dead simple

"Heavy metal and drop D is a match made in heaven," Soundgarden’s Kim Thayil once said, and for heavy rock riffs and thick-sounding chords, drop D is hard to beat.

It's a simple one to set up, too: the sixth string is lowered by a whole step from E to D, while the other five strings remain in standard tuning. Easy!
