Standard (E A D G B E) popular

E2 A2 D3 G3 B3 E4

The default guitar tuning: perfect fourths everywhere except a major third between G and B. Almost every chord book, tab and method assumes it.

Drop D (D A D G B E) popular

D2 A2 D3 G3 B3 E4

Lower only the 6th string a whole step. Power chords on the bottom three strings become one-finger shapes, and a low D drone opens up for keys of D…

DADGAD popular

D2 A2 D3 G3 A3 D4

Modal, suspended-sounding tuning with no third. A staple of Celtic fingerstyle and accompaniment.

Open G (D G D G B D) popular

D2 G2 D3 G3 B3 D4

Strumming the open strings sounds a G major chord. A slide and blues favourite; with the 6th string removed it is the classic five-string rhythm…

Open D (D A D F♯ A D) popular

D2 A2 D3 F#3 A3 D4

Open strings form a D major chord. Rich, resonant and ideal for slide guitar and folk fingerpicking.

Open E (E B E G♯ B E)

E2 B2 E3 G#3 B3 E4

Same shape as open D, a whole step higher. Bright, but raises string tension — many players prefer open D with a capo.

Open C (C G C G C E)

C2 G2 C3 G3 C4 E4

A wide, piano-like open C major chord. Deep bass and shimmering top.

Open A (E A E A C♯ E)

E2 A2 E3 A3 C#4 E4

Open-chord tuning a whole step above open G — useful for slide in A.

Half Step Down (E♭ A♭ D♭ G♭ B♭ E♭) popular

Eb2 Ab2 Db3 Gb3 Bb3 Eb4

Every string lowered a semitone. Slinkier feel, easier bends and a slightly darker sound used by many rock bands.

Whole Step Down (D G C F A D)

D2 G2 C3 F3 A3 D4

Every string lowered a whole step; same chord shapes, everything sounds a tone lower.

Drop C (C G C F A D)

C2 G2 C3 F3 A3 D4

Whole-step-down tuning with the 6th string dropped a further tone. Heavy, one-finger power chords.

Drop B (B F♯ B E G♯ C♯)

B1 F#2 B2 E3 G#3 C#4

Very low drop tuning for modern metal; usually needs heavier strings.

Open D Minor (D A D F A D)

D2 A2 D3 F3 A3 D4

Open D with the third lowered — a haunting minor chord (cross-note tuning).

Nashville (high-strung)

E3 A3 D4 G4 B3 E4

Strings 3–6 replaced by the thin octave strings of a 12-string set. Sparkling, harp-like doubling for recordings.

All Fourths (E A D G C F)

E2 A2 D3 G3 C4 F4

Perfect fourths across every string so chord and scale shapes never shift. Popular with jazz players.

Baritone (B E A D F♯ B)

B1 E2 A2 D3 F#3 B3

Standard intervals a fourth lower, for baritone guitars with a longer scale.

Strings listed 6 → 1 (low E to high E).
