Guitar tunings
Standard is built in; the everyday four arrive as presets you can delete — and recover below. Then the next ring out.
Scan a code with your iPhone camera — or open the link — and Nitpitch offers the tuning: load it once, or keep it. Without the app, the link shows the same details you see here.
Ships in the app
These arrive with the app as ordinary presets. If you deleted one and want it back, it's one scan away — same name, same pitches.
Drop D
D2 A2 D3 G3 B3 E4
The sixth string down a step. One-finger power chords, a deeper floor — the first alternate tuning most players meet.

DADGAD
D2 A2 D3 G3 A3 D4
The Celtic modal standard — neither major nor minor until you commit.

Open G
D2 G2 D3 G3 B3 D4
The open G chord — Keith Richards' home (minus his missing sixth string), and half the Delta.

Half-step down
D♯2 G♯2 C♯3 F♯3 A♯3 D♯4
Everything down a semitone: slacker feel, darker voice, and a kinder key for singers. Hendrix lived here.

Open tunings
The open strings sound a chord — slide players' home ground, and the fastest way into a new song's world.
Open D
D2 A2 D3 F♯3 A3 D4
D A D F♯ A D — "Vestapol". The bedrock open tuning: slide, fingerstyle, and a hundred years of blues.
https://nitpitch.app/t#djF8Z3VpdGFyfDM4LDQ1LDUwLDU0LDU3LDYyfHx8T3BlbiBE

Open E
E2 B2 E3 G♯3 B3 E4
Open D's shape a step up, without a capo. Duane Allman's slide tuning; harder on the neck — some prefer Open D with a capo 2.

Open C
C2 G2 C3 G3 C4 E4
C G C G C E — deep and wide. Devin Townsend and a lot of modern fingerstyle live here.
https://nitpitch.app/t#djF8Z3VpdGFyfDM2LDQzLDQ4LDU1LDYwLDY0fHx8T3BlbiBD

Open A
E2 A2 E3 A3 C♯4 E4
E A E A C♯ E — Open G's cousin a step up, with the top string kept at E. Delta blues slide territory.

Open D minor
D2 A2 D3 F3 A3 D4
D A D F A D — one string from Open D, a world apart. The darkest of the common opens.

Dropped & lowered
Double drop D
D2 A2 D3 G3 B3 D4
Both E strings down to D. Neil Young's home tuning — Cinnamon Girl, Ohio.
https://nitpitch.app/t#djF8Z3VpdGFyfDM4LDQ1LDUwLDU1LDU5LDYyfHx8RG91YmxlIGRyb3AgRA

Full step down
D2 G2 C3 F3 A3 D4
Standard, one whole step lower. Slacker tension, darker voice — from SRV to doom.
https://nitpitch.app/t#djF8Z3VpdGFyfDM4LDQzLDQ4LDUzLDU3LDYyfHx8RnVsbCBzdGVwIGRvd24

Drop C
C2 G2 C3 F3 A3 D4
Full step down with the sixth dropped further to C — the workhorse of modern heavy rhythm playing.

Folk & modal
Orkney
C2 G2 D3 G3 C4 D4
C G D G C D — neither major nor minor, all drone. A favorite of the Scottish and Irish fingerstyle school.
