Ukulele Tuning Notes Explained — The Complete GCEA Guide

Every great ukulele journey starts with one question: what is the right tune of ukulele? Whether you're picking up a soprano, concert, or tenor uke, understanding standard GCEA tuning is the foundation of everything you'll play. This guide breaks down ukulele string notes one by one, maps out every note on the fretboard, and answers the most common questions beginners ask. By the time you finish reading, you'll know your instrument inside and out.

What Is the Standard Tune of Ukulele?

The standard tune of ukulele is G-C-E-A. This applies to soprano, concert, and tenor ukuleles — the three most common sizes. Baritone ukuleles use a different tuning (D-G-B-E), but for the vast majority of players, GCEA is what you need to know.

The strings are numbered from 4 to 1, counting from the string closest to your face (when holding the ukulele in playing position) down to the string closest to the floor. Many beginners find this counter-intuitive, but here's the logic: the 1st string is the one you reach first when you look down at the fretboard.

String #	Note Name	Scientific Pitch	Frequency	Position
4 (top)	G	G4	392 Hz	Closest to your face
3	C	C4 (Middle C)	262 Hz	Middle
2	E	E4	330 Hz	Middle
1 (bottom)	A	A4	440 Hz	Closest to floor

Notice something interesting? The G string (4th) is tuned higher than the C string (3rd) below it. This is called re-entrant tuning, and it's what gives the ukulele its distinctive bright, cheerful voice.

Memory trick: "Good Cooks Eat Always" — G, C, E, A, from top to bottom. Say it once and you'll never forget your ukulele strings and notes.

Ukulele String Notes: Open Strings Explained

Open strings on ukulele are the building blocks of every chord, scale, and melody you'll ever play.

Each Open String in Detail

4th String — G (392 Hz): The G string is the one closest to your face. In standard re-entrant tuning, this G is actually G4 — higher in pitch than the C string below it. This is the string that most clearly defines the ukulele's signature sound. If you switch to low g ukulele strings, this becomes G3, one octave lower.

3rd String — C (262 Hz): The C string is the lowest-pitched string in standard tuning and produces middle C — the same note as the middle C on a piano. This is the anchor of your ukulele's tonal range and the root of the most common beginner chord.

2nd String — E (330 Hz): The E string sits in the middle of the ukulele's vocal range. It's a perfect fifth above A and a major third above C, making it essential for the instrument's harmonic character.

1st String — A (440 Hz): The A string is the highest-pitched string and the one closest to the floor. A4 at 440 Hz is the standard concert pitch used to tune orchestras worldwide. This is often the first string you tune, serving as a reference for the others.

Memorize these four notes — they're the gateway to everything else.

Ukulele Notes on Fretboard — Complete Layout

Every fret you press raises the pitch by one semitone (half step). Learning the fretboard notes ukulele layout unlocks the ability to play melodies, move chords up the neck, and improvise with confidence.

The Chromatic Pattern

The musical alphabet has 12 notes: A, A#/Bb, B, C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab. Starting from any open string, each fret moves you up one note in this sequence. For example, on the C string (3rd string):

Fret	0 (open)	1	2	3	4	5	6	7	8	9	10	11	12
C String	C	C#	D	D#	E	F	F#	G	G#	A	A#	B	C

Notice that at the 12th fret, the note repeats — it's the same note as the open string, just one octave higher. This pattern is identical for every string; only the starting note changes. Understanding notes on the ukulele fretboard this way means you can find any note on any string.

Natural Notes vs. Accidentals

There are 7 natural notes (A, B, C, D, E, F, G) and 5 accidentals (the sharps and flats between them). The natural notes on the ukulele are the same white keys you'd find on a piano. 

A helpful pattern: between most natural notes there's a sharp/flat, except between B→C and E→F — these pairs are only one semitone apart with no black key between them. This is why you'll never see B# or E# on a standard fretboard chart.

Low G Ukulele Strings: An Alternative Tuning

While standard high-G tuning is what most players start with, low g ukulele strings offer a different sonic palette. In low G tuning, the 4th string is tuned to G3 — one full octave lower than the standard G4. The result is a warmer, fuller sound with extended bass range.

To switch to low G, you need a dedicated low g ukulele string — you can't simply tune a standard high G string down an octave; it would be too loose to play. Low G strings are typically wound metal or thicker fluorocarbon, designed to maintain proper tension at the lower pitch. When restringing, use a low g ukulele tuner (any chromatic tuner works) to get the G3 pitch accurate.

Tuning Type	4th String Note	Sound Character	Best For
High G (Standard)	G4 (392 Hz)	Bright, traditional island tone	Strumming, traditional Hawaiian music
Low G	G3 (196 Hz)	Warm, fuller, more guitar-like	Fingerpicking, jazz, solo arrangements

Low G tuning doesn't change the notes on a ukulele for strings 3, 2, and 1 — only the 4th string is affected. All your chord shapes remain the same; they just sound richer on the bottom end. If you're curious about expanding your tonal range, the Ukutune Replacement Strings set includes a low G option to get you started.

How to Read Music Notes for Ukulele

Learning how to read music notes for ukulele opens up a world of songs beyond simple chord charts. There are two main systems: standard notation (the five-line staff with note heads) and tablature (four horizontal lines representing your four strings). Most ukulele players start with tab — it's simpler and more intuitive.

Understanding Ukulele Tablature

Ukulele tab uses four lines — the top line represents the A string (1st), and the bottom line represents the G string (4th). Numbers on each line tell you which fret to press. A "0" means play the open string; a "3" on the top line means press the 3rd fret of the A string. 

Standard Notation Basics

If you want to go deeper, standard notation places your ukulele tune notes on a five-line staff. The open C string (middle C) sits on the first ledger line below the treble clef staff. The open E string sits on the bottom line of the staff. The open G string sits on the second line. And the open A string sits on the second space. Knowing where these notes on a ukulele land on the staff connects your instrument to the broader world of written music.

Exploring Alternate Ukulele Tune Notes

Some songs call for different tunings to match the original recording or to make certain chord voicings easier.

Baritone Tuning (D-G-B-E)

The baritone ukulele uses D-G-B-E — the same as the highest four strings of a guitar, D (3rd string), G (2nd string), B (1st string with the highest pitch), and E (4th string as the lowest).

Open Tunings

Some players experiment with open tunings where strumming all open strings produces a full chord. Open e tuning big yellow taxi on ukulele is a popular example — Joni Mitchell's classic uses an open E tuning on guitar, and ukulele players adapt it by tuning to E-B-E-G# to match the song's distinctive sound. Open tunings make slide playing and certain fingerpicking patterns much easier.

Slack-Key Tuning

Traditional Hawaiian slack-key guitar tuning has influenced ukulele players too. Common slack-key ukulele tunings include G-C-E-G (open C tuning) and F-C-E-A (dropping the G string a whole step). These alternate fretboard notes ukulele configurations give you new chord voicings without learning new shapes.
