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.

This compares your input with the reference you supply. It is not a certified calibration. Only numbers are saved, never audio.

KNOW YOUR TUNING

C♯ standard: C♯ F♯ B E G♯ C♯

Lower every string three semitones from standard. This is also called D flat standard. The fourth string becomes B and the third becomes E.

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

THE TUNEGUITAR GUIDE

Understand C♯ standard

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

A minor-third transposition

Lowering every string three semitones preserves standard fingering relationships. An E shape sounds C sharp, an A shape F sharp and a G shape E. This is a uniform transposition, not a dropped-bass layout. The fourth string is B2, which can look unfamiliar if you normally associate B with the second string.

A direct route from Drop B

Drop B and C sharp standard have the same upper five strings. Raise only the sixth string from B1 to C sharp2 to switch between them. If you instead start in Drop C sharp, its upper five strings must drop a whole step to reach C sharp standard. Naming the starting tuning avoids a misleading instruction such as simply 'tune down'.

Reading flats without a second preset

D-flat standard and C-sharp standard describe the same equal-tempered targets. Some note pairs are spelled differently by notation convention, but the frequencies are unchanged. Use the six-note sequence and octaves when comparing sources, especially where a tuner chooses B rather than C flat. Do not retune for spelling alone.

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 C♯ standard

Is C sharp standard the same as Drop C sharp?

No. C sharp standard lowers every string equally. Drop C sharp lowers the thickest string further relative to the other five.

Which chord sounds when I play an E-major shape?

C-sharp major. This tuning moves every standard string down three semitones, so the fingering keeps its intervals while its sounding root moves. A familiar A-major shape similarly becomes F-sharp major.

Can I move to Drop B without retuning every string?

Yes. From C-sharp standard, lower only the sixth string from C-sharp2 to B1. The remaining F-sharp2 B2 E3 G-sharp3 C-sharp4 targets already match six-string Drop B. Recheck them after lowering the bass.
