Drop C Tuner (C G C F A D)

The universal concert tuning used across rock, pop, acoustic, blues, and classical guitar.

The 6th string is dropped one whole step from E down to D, enabling fast one-finger power chords.

Every string tuned down one semitone (Eb Ab Db Gb Bb Eb) for warmer acoustic timbre and easier bends.

Every string lowered by one full whole step (D G C F A D) for dark, heavy chords.

Modal D suspended tuning renowned for open, ringing acoustic harmonies in Celtic and fingerstyle folk.

Strumming all open strings produces a pure G major triad. The definitive sound of the Rolling Stones.

An open strum rings out a full D major chord (D A D F# A D). Standard for blues slide guitar.

Open strum produces an E major chord. Duane Allman / Derek Trucks slide signature.

An expansive open tuning sounding a deep C major triad (CGCGCE), favored for lush acoustic fingerstyle and drone acoustic.

Both the 1st and 6th outer strings are dropped one whole step to D, creating a symmetrical D-A-D-G-B-D tuning.

An evocative modal minor tuning (C G C Eb G Bb) creating an open C minor 11 chord with haunting, cinematic overtones.

Standard seven-string guitar tuning (BEADGBE) adding a heavy low B fifth below standard low E.

Standard twelve-string acoustic/electric concert tuning with octave pairings on the lower 4 courses and unisons on the top 2 courses.
