What are the exact frequencies for standard ukulele tuning (gCEA)?

At concert pitch (A440), standard soprano, concert, and tenor ukuleles are tuned to: 4th String (G4) = 392.00 Hz, 3rd String (C4) = 261.63 Hz, 2nd String (E4) = 329.63 Hz, and 1st String (A4) = 440.00 Hz.

What is the difference in Hertz between Low G and High G ukulele strings?

A standard High G4 vibrates at 392.00 Hz, while a Low G3 vibrates at 196.00 Hz. The Low G vibrates at exactly half the frequency, sounding one full octave (12 semitones) lower.

What are the frequencies for a Baritone ukulele (DGBE)?

Baritone ukulele strings are tuned to: 4th String (D3) = 146.83 Hz, 3rd String (G3) = 196.00 Hz, 2nd String (B3) = 246.94 Hz, and 1st String (E4) = 329.63 Hz.

What are cents in musical pitch measurement?

A cent is a logarithmic unit of measure used for musical intervals. There are 100 cents between each adjacent half-step (semitone) on the chromatic scale. A note is generally considered musically in tune when it is within ±5 cents of target pitch.

Ukulele Tuning Notes & Frequencies Chart (Complete Pitch Reference)

Published by Ukulele Tuners Editorial Team•6 min read•Standard A440 Pitch

Whether you are calibrating a digital audio workstation (DAW), fine-tuning a microphone pitch detector, or setting up a new set of strings, knowing the exact physical frequencies (in Hertz) for every ukulele note gives you complete control over your instrument's intonation.

1. Standard Ukulele Tuning (gCEA)

Soprano, Concert & Tenor

Standard tuning is re-entrant: the 4th string (G4) is tuned higher than the 3rd string (C4). Standard international concert pitch references A4 = 440.00 Hz.

String Number	Scientific Pitch	Exact Frequency (Hz)	Wavelength (cm)	Audio Register
4th String	G4	392.00 Hz	87.5 cm	Treble (High G)
3rd String	C4	261.63 Hz	131.1 cm	Middle C (Lowest pitch)
2nd String	E4	329.63 Hz	104.1 cm	Mid-Treble
1st String	A4	440.00 Hz	78.0 cm	Concert A (Highest open pitch)

2. Low G Ukulele Tuning (GCEA)

Linear Tenor & Concert

In Low G tuning, the 4th string is dropped an entire octave from G4 (392 Hz) to G3 (196 Hz), creating a pure linear ascending scale.

String Number	Pitch	Frequency (Hz)	Comparison to High G
4th String	G3 (Low G)	196.00 Hz	-196 Hz (12 semitones lower)
3rd String	C4	261.63 Hz	Identical
2nd String	E4	329.63 Hz	Identical
1st String	A4	440.00 Hz	Identical

3. Baritone Ukulele Tuning (DGBE)

Guitar Top-4 Match

Baritone ukuleles feature longer scale lengths (19 to 21 inches) and are tuned to the exact pitches of the top 4 strings of an acoustic guitar.

String Number	Pitch	Frequency (Hz)	Guitar Match
4th String	D3	146.83 Hz	Guitar 4th string (open D)
3rd String	G3	196.00 Hz	Guitar 3rd string (open G)
2nd String	B3	246.94 Hz	Guitar 2nd string (open B)
1st String	E4	329.63 Hz	Guitar 1st string (high E)

4. English D-Tuning (aDF#B)

Traditional Vintage Vaudeville

Popular in the 1920s and still widely used in Canadian and British school music programs, D-Tuning tightens all strings one full step (two semitones) higher for extra projection and crispness on small soprano ukuleles.

Frequency Reference FAQs

Why is A4 set to 440 Hz?

In 1939, an international conference established 440 Hz for the A above Middle C (A4) as the worldwide standard pitch (Concert Pitch / Stuttgart pitch). All modern digital tuners and audio gear calibrate relative to this standard.

Can I tune my ukulele to 432 Hz?

Yes, some musicians prefer the slightly lower, warmer resonance of A=432 Hz. When calibrated to 432 Hz, all strings shift flat by approximately 31.8 cents: G4 becomes 384.87 Hz, C4 becomes 256.87 Hz, E4 becomes 323.63 Hz, and A4 becomes 432.00 Hz.
