Over the last half century, this tuning has become immensely popular to the point where it is a widespread common knowledge among all guitarists and most music tutors, as certain songs from the rock canon have edged their way through the door of most classrooms to be taught in various music syllabuses throughout the western world. Thus, you would be hard pressed to find a band, at least in the rock and heavy metal sphere, that has not, at some point, used drop D tuning to further their musical endeavours and to dim the lights of the mood of a certain track or set of tracks.
