D♭ tuning, also called C♯ tuning, is an alternative guitar tuning. Each string is one and one half steps lower than in standard tuning, or one half step lower than D tuning. The resulting notes can be described as D♭-G♭-B-E-A♭-D♭ or (less often) as C♯-F♯-B-E-G♯-C♯. "Extremely slack," it is very popular amongst alternative and heavy rock bands because it has a darker and lower-pitched sound compared to E standard.
