• OVERVIEW •
The same interval pattern as Drop D, but everything is moved down two further semitones. Brings a loose, chaotic, imperfect texture: total string tension is lowered by around 25% – equivalent to a ~40lb/18kg drop on a steel-string acoustic (an instrument on which EADGBE tension can exceed 180lb/82kg…hence you need the truss rod!).
One of my all-time favourite versatile acoustic tunings: allowing for wider bends and expressive articulations while also balancing well with instrument timbres of all shades. Perhaps best to jump it up a half-step on short-neck axes…or you can drop it down even lower for some slack-buzzing magic (n.b. Some call CGCFAD ‘Drop C’…but for clarity I’ve reserved that title for CADGBE).
Harmony: C6/9(sus4) | 1-5-1-4-6-2

• SOUNDS •
CGCFAD is most often found on bespoke, heavy-strung electric cuts. While far less popular than its Drop D transposition, it does turn up on some prominent songs: e.g. Question! (System of a Down), Ill Wind (Jonny Greenwood), Vox Stellarum (Arch Enemy), Radiant Eclipse (Avenged Sevenfold), Nottingham Lace (Buckethead), She Found Now (My Bloody Valentine, -1) – as well as most of Metallica’s St. Anger album.
- Question! – System of a Down (2005):
“Question! mixes intricate arpeggios with pounding riffs, running both through several different time signatures…drawing on the group’s Armenian heritage, a tradition famous for grooves of 10/8 and beyond…As ever, the first step is to tap along. First, isolate the three main rhythm loops: 9 subdivided as ‘3-2-2-2’ (intro & verse), 10 subdivided as ‘3-3-2-2’ (heavy riffs), and 12 subdivided as ‘3-3-3-3’ (chorus)…” (from my Odd-Time Songwriting lesson for Guitar World)

- CGCFAD songs: check out the huge track list on the Drop C Wikipedia article (although it has to be said…Wikipedia, despite its many areas of strength, is an absolutely terrible source of tuning info, and the Drop C page’s citations are pretty thin – plus, I haven’t heard of most of the artists, who range from Swedish thrash acts to obscure Japanese electronicore – let me know what you can discern!)
