About Drop C Tuning
Drop C tuning (C-G-C-F-A-D) drops every string one whole step below Drop D, delivering a massive, brutal low-end that has defined the sound of modern metalcore, post-hardcore, and nu-metal. The low C string provides earth-shaking power chords with a single finger while maintaining familiar Drop D shapes — just two frets lower.
From System of a Down's iconic riffs to Killswitch Engage's crushing breakdowns, Drop C has become the standard tuning for heavy music that needs to sound bigger than standard Drop D. It bridges the gap between standard guitar territory and the extended range of 7-string guitars, making it accessible to players who want heavier tones without buying a new instrument.
Notable artists: System of a Down, Killswitch Engage, Bullet for My Valentine, As I Lay Dying, August Burns Red
Best for: Modern metalcore breakdowns, heavy power chord riffs, nu-metal grooves, and aggressive rhythm playing
