Every song you’ll ever play is made from just twelve notes, and your ukulele holds all of them across its four strings. Learning the ukulele notes is the step that takes you from copying chord shapes to understanding your instrument: you’ll be able to find any note on demand, work out chords for yourself, and talk to other musicians without guesswork.
Below you’ll find the string names, the twelve‑note system, and how the whole fretboard repeats itself, finishing with a ukulele notes chart and an interactive fretboard you can tap to hear every note on your instrument.
Interactive Ukulele Notes Chart
This interactive fretboard shows every note on every string from open to the 12th fret. Tap any note to hear how it sounds, switch the labels between sharps and flats, or pick a note name to light up that note everywhere on the fretboard.
Try lighting up “E” and notice how it appears in five different places; that’s the fretboard starting to become readable.

Tap any note to hear how it sounds. Pick a note name to light up that note everywhere on the fretboard. Every note repeats one octave higher starting at the 12th fret. On narrow screens the chart scrolls sideways.
The Four Strings: G, C, E, A
From the string closest to your chin to the string closest to the floor, the open ukulele strings are G, C, E, and A. The classic mnemonic “Good Children Eat Apples” locks them in, and the tuning is called reentrant, meaning that first G is a high G, sitting higher in pitch than the C and E below it, which gives the ukulele its bright, bouncy character.
If you’re unsure whether your strings are in tune, check them against our online ukulele tuner first; everything below depends on your instrument being in tune.
The Twelve Notes: How the Musical Alphabet Works
Music uses a repeating cycle of twelve note names: C, C♯, D, D♯, E, F, F♯, G, G♯, A, A♯, B, and then it starts over at C again. Two note names can be enharmonic, the same sound with two spellings, like C♯ and D♭, which are the same key on the piano and the same fret on your ukulele.
Sharps (♯) raise a note by one fret, flats (♭) lower it by one fret, and either spelling is correct; classical music leans toward flats, pop and ukulele culture lean toward sharps.
Notice the pattern of the list above: some note pairs, like E→F and B→C, have nothing between them; they’re directly adjacent frets. Every other pair has a sharp/flat note in between. That’s the entire rule for naming notes, and it’s why the fretboard below has no “E♯” or “B♯” labels anywhere.
Each Fret Is One Note
Pressing a string against a fret shortens it, which makes it vibrate faster and sound higher. The rule is simple: every fret you move up raises the note by one step in the twelve‑note cycle. Fret 1 raises the open string’s note by one, fret 2 by two, and so on. The C string, played open, sounds a C; at the 2nd fret it becomes a D, at the 4th an E, and at the 7th a G.
Move over one string and the whole pattern starts again, so if you know the notes on one string, you can work out any other string’s notes with the same cycle.
Why the Notes Repeat at the 12th Fret
The most important landmark on the fretboard is the 12th fret, and most ukuleles mark it with two inlay dots. Press any string there and you hear the same note name as the open string, one octave higher: the G string at the 12th fret is a G, the C string at the 12th is a C, and so on. That’s no coincidence: halving a vibrating string’s length always doubles its pitch, and twelve steps lands you there.
The fretboard is a twelve-fret pattern that repeats, so learn the notes from the open strings to the 12th fret and you know the whole instrument. You can see the labels flip back to G, C, E, A in the chart at the 12th-fret column.
How to Learn the Fretboard Faster
Landmarks beat brute force: learn a few anchor points and build outward from them. The method below is how most teachers break it down, and it works in layers.
- Nail the open strings first. G, C, E, A, until it’s automatic. These are your anchors.
- Learn the E string. It has the fewest notes you care about early on (E, F, G, A, B, C at the 5th fret, the notes of your most-used chords), and it sits right under your fingers.
- Use the 5th fret as a cross-check. The C string at the 5th fret is an F, and the E string at the 5th fret is an A, easy checkpoints to confirm you’re on the right track.
- Learn one note at a time, everywhere. Pick “A” today and find every A on the board using the “light up” feature above. Tomorrow, pick G. A note per day, and in under two weeks the board is yours.
- Attach notes to chords you already play. A C chord (0-0-0-3) is just the notes C, E, G; a G chord (0-2-3-2) is G, B, D. Every chord you know becomes a memory peg for its notes.
Once the notes are in place, they start paying you back: you can find chord tones for arranging songs, figure out melodies by ear, and understand how chords are built instead of copying diagrams. If you’re still building your basic chord vocabulary, our easy ukulele chords guide pairs well with this stage.
Frequently Asked Questions
What are the notes on a ukulele in standard tuning?
G, C, E, A, from the string nearest your chin to the one nearest the floor. This is standard reentrant tuning on a soprano, concert, or tenor ukulele. Baritone ukuleles tune differently (D, G, B, E), so a notes chart for standard tuning won’t match a baritone.
How many notes does a ukulele have?
There are only twelve different note names in music, and every one of them appears on your ukulele multiple times at different octaves. On a typical soprano with 12 usable frets you have 52 playable positions (4 strings × 13 positions including the open strings), covering about three octaves of sound.
Which note is on which string?
Start from each string’s open note and count one note per fret: the G string runs G, G♯, A … ; the C string runs C, C♯, D …; the E string runs E, F, F♯ …; and the A string runs A, A♯, B … . The interactive chart above shows all four rows at once, and tapping any note plays it so you can check by ear.
Do I need to memorize the whole fretboard to play songs?
No. Plenty of excellent players never leave the world of chord diagrams. But knowing the notes makes you faster at finding chords, transposing songs, and playing melodies, and it demystifies everything else you learn. Start with the open strings, the E string, and the 12th-fret repeat; the rest fills in naturally.
The ukulele is one of the friendliest instruments for learning notes, because twelve steps always brings you back to the start. Take the chart above, tap around, light up a new note each day, and the fretboard will start reading like a language you’ve always known.
