A gentle ping follows a steady note within 5 cents. Its volume follows the sound slider. Microphone audio stays on your device.

Check your intonation.

Compare one open string with the same string pressed at fret 12. Remove your capo and mute the other strings.

  1. 1. Tune and measure the open string
  2. 2. Press at fret 12 and measure again

Press just behind fret 12 with normal pressure. Do not play a harmonic. Repeat the comparison to confirm the result.

Check your six strings.

Press start, then sweep gently across all six open strings, from thickest to thinnest. Let them ring together.

Experimental: overlapping notes can be unclear. Select any result to measure that string alone in this window.

Check a known reference.

Play a steady reference from another device or instrument whose frequency you know. Enter that frequency below.

Baritone A standard: A D G C E A

A standard is seven semitones below a regular six-string guitar. It is intended for an instrument and strings suited to that range. Tune gently and recheck the full set.

The table shows the open-string setup at A4 = 440 Hz. For capo pitches, use the capo controls above.

THE TUNEGUITAR GUIDE

Understand Baritone A standard

TuneGuitar guide · Updated 6 October 2026 · How we prepare our guides

A standard and Drop A have different upper strings

This baritone layout is A D G C E A. Six-string Drop A is A E A D F sharp B. Sharing A1 as a lowest note does not make them interchangeable. Check string 5: D belongs to A standard, E to the dropped layout. The ordinary chord-shape relationships survive only in the uniform standard transposition.

A fifth below familiar fingerings

Every string is seven semitones below regular standard, so an E shape sounds A and an A shape sounds D. This makes the guitar sit in a much lower register without changing relative fingerings. Write sounding chord names when sharing a part with a keyboard player rather than relying on the names of your shapes.

Low-frequency measurement takes care

The lowest A is 55 Hz. Give it a clear isolated signal and let the initial attack settle. A2 at 110 Hz is the next octave, not evidence that you should halve the string's tension again. Use the selected-string target and a suitable baritone setup. The numerical target cannot determine whether a particular scale length and string gauge will feel stable.

Your string-by-string route from standard

This is a comparison of target pitches, not a recommendation to use every tuning on every guitar. Start from the tuning your instrument actually has. Use the directions and the octave labels together.

GOOD TO KNOW

Questions about Baritone A standard

How does A standard differ from Drop A?

A standard is A D G C E A on six strings. Six-string Drop A is A E A D F sharp B. Their lowest note matches, but their other targets differ.

How do I change from baritone B to baritone A?

Each of the six targets moves down two semitones, giving A1 D2 G2 C3 E3 A3. Do not lower only the bass: that would lead toward six-string Drop A instead. Check the resulting feel against the strings and setup on your instrument.

What does a familiar E-major shape sound like here?

A major. A-standard baritone places each standard target seven semitones lower, so a standard E-root shape acquires an A root. The highest open A is A3; the lowest is A1, two octaves below it.
