How to write a song on ukulele: chords, strums and a melody

To write a song on ukulele, tune to G C E A, pick four chords you can already change between (C, Am, F and G are the classic set) and loop them with one strumming pattern. Hum over the loop and record every attempt. When a two-bar phrase sticks, fit words to its rhythm and put the title on its strongest note. Keep the melody within about an octave, because the ukulele’s chords sit in a narrow, bright band around middle C. Then check the key against your voice and, if the chorus strains, move it with a capo or another set of shapes. Thirty minutes is enough for a first verse and chorus.

Below: what the ukulele’s tuning means for your song, the four shapes and the loops to start from, strumming patterns used as rhythm ideas, how to write a melody over such a small instrument, keys and capo, an original worked example, a 30-minute exercise and how to record it.

Tune to G C E A first, and what that tuning does to your song

Standard ukulele tuning, from the string nearest your chin (4th) to the one nearest the floor (1st), is G C E A. It’s a re-entrant tuning: the 4th string isn’t the lowest note. Its G sits above the C next to it, so the lowest note on the instrument is the open 3rd string, middle C.

String	Note	Frequency
4th (G)	G4	392.00 Hz
3rd (C)	C4, middle C	261.63 Hz
2nd (E)	E4	329.63 Hz
1st (A)	A4	440.00 Hz

The free tuner below works with the ukulele: choose Ukulele in the Instrument menu, the tuning switches to Standard (G C E A), then press Start and pluck one string at a time. Your audio never leaves your device.

Soprano, concert and tenor ukuleles share this tuning, so every shape in this article works on all three. The baritone is the exception: it’s tuned D G B E, like the four thinnest strings of a guitar, and the same shapes give other chords (a C shape sounds as G).

What the tuning means when you write:

• There is almost no bass. The lowest note is middle C, and in F (2 0 1 0) or G (0 2 3 2) the lowest note isn’t even the root. The song sounds light, so its drive comes from your strumming hand, not from a bass line.
• The chords live in one narrow band, roughly the octave above middle C. A higher voice sings in that same band and a lower voice sings an octave below it. Either way, your melody has to stand out from a small, bright block of notes.
• The top string plays a tune of its own. More on that in the melody section; it’s the most useful trick on the instrument.

The four shapes: C, Am, F and G

The numbers below are frets from the 4th string (G) to the 1st (A); 0 means play it open. Each chord page shows the diagram on ukulele, guitar and piano, and plays the chord: C, Am, F and G.

Chord	Frets (G C E A)	Fingers	Tip
C	0 0 0 3	Ring finger, 1st string, 3rd fret	The easiest chord on the instrument
Am	2 0 0 0	Middle finger, 4th string, 2nd fret	One finger; C to Am is a single move
F	2 0 1 0	Am plus the index on the 2nd string, 1st fret	Keep the middle finger down from Am
G	0 2 3 2	Index 3rd string, middle 1st string, ring 2nd string	The hard one of the four: practice F to G
G7 (later)	0 2 1 2	Three fingers	Pulls hard back to C
Dm (later)	2 2 1 0	Three fingers	Adds a sadder color in C
E7 (later)	1 2 0 2	Three fingers	The chord that leads home in A minor

Practice the changes before you write. Loop each pair (C to Am, Am to F, F to G, G to C) for one minute against the tap tempo metronome at 60 BPM, one strum per beat, and only speed up when the change lands on the beat. F to G is where most first songs stall: if it still does, write the first verse with C, Am and F only.

Four-chord loops to start from

A first song doesn’t need original chords. It needs a loop that supports what you’ll sing. Each link opens the free chord progression player with the loop set, so you can hear it, sing over it or play along.

Loop	Chords	Feel	Hear it
I–V–vi–IV	C–G–Am–F	Open, sing-along	Open
I–vi–IV–V	C–Am–F–G	Warm, a little nostalgic	Open
vi–IV–I–V	Am–F–C–G	Starts serious, then lifts	Open
I–IV–I–V	C–F–C–G	Plain, campfire, kids’ songs	Open
i–iv–V7–i	Am–Dm–E7–Am	Minor, wistful	Open

All five use only the shapes in the table above. For the theory behind each loop and many more to try, see chord progressions for songwriting.

What to listen for: after the count-in (0:00–0:02), each chord lasts one bar of almost three seconds: C at 0:02, Am at about 0:05, F at 0:08 and G at 0:11, then the loop again from about 0:14. The G at 0:11 leaves you hanging, which is why the loop keeps turning. It’s a synthesized teaching example with an arpeggio, not a ukulele recording; on the uke you’d play it with the four shapes above.

What to listen for: the same four chords, reordered to start on Am at 0:02 and strummed: F at about 0:05, C at 0:07 and G just before 0:10, then the loop again from about 0:12. Starting on the minor chord makes the same shapes sound more serious. If your song is about something you miss, try this order before you change any chord.

Strumming patterns as rhythm ideas

On ukulele the strumming hand does the work a drummer would. Count eighth notes out loud, “1 & 2 & 3 & 4 &”, and keep the hand moving down on the numbers and up on the ”&“s, even when it doesn’t touch the strings. D is a downstroke, U an upstroke, - a pass without touching and X a chuck: the side of your strumming hand lands on the strings as you strum down, so they click instead of ringing.

Pattern	Strums on “1 & 2 & 3 & 4 &“	Feel	Use it for
A. Four downs	D - D - D - D -	Steady, plain	A first song, verses that tell a story
B. Island strum	D - D U - U D U	Bouncy, the sound people picture	Most choruses
C. Chuck backbeat	D - X U D U X U	Snappy, like a snare on 2 and 4	Upbeat pop with no drummer
D. Off-beat	- - D U - - D U	Laid back, reggae feel	Relaxed, sunny songs
E. Waltz, in 3/4 (“1 & 2 & 3 &“)	D - D U D U	Swaying	Lullabies, sad songs, songs that look back

The island strum is usually written D – DU – UDU: the downstroke on beat 3 is the one that never touches the strings, and that gap gives the bounce.

Turn the strum into the rhythm of a line. The hits of a pattern are already a rhythm a voice can copy. In the island strum, the strings sound on 1, 2, 2&, 3&, 4 and 4&: six hits, so speak a six-syllable line on them. “No-bo-dy needs me yet” puts “needs” on the 3&, the off-beat right after the gap, and the line bounces the same way the strum does. Four downs give you four even syllables per bar, “shirts on the line”, which suits a calm verse. Speak the line first, then sing it on any notes: you have the rhythm of a melody before you have the tune.

One more idea that costs nothing: change the strum between sections. Pattern A in the verse and pattern B or C in the chorus lifts the chorus even if the chords barely change.

Writing a melody over the ukulele (it has a small range)

The ukulele’s first-position chords all fit between middle C and the C above it. Your melody needs room around that band, so keep the whole tune within about an octave and give the verse and the chorus different heights.

Use the top string as a starting tune. In C–Am–F–G, the 1st string plays C, A, A and B by itself (fret 3, open, open, fret 2). In C–G–Am–F it plays C, B, A, A: a line that falls one step at a time. Sing those notes over the loop first; they always fit. Then move away from them. When your melody rises while the top string falls, the two lines pull against each other and the phrase sounds more alive.

Hum, then find the notes. Record a hum over the loop, then pluck the 1st and 2nd strings, frets 0 to 5, until you find the note you hummed. If you can’t tell, sing it into what note am I singing and it names the note. Write the melody’s lowest and highest notes at the top of your page; you’ll need them for the key.

What to listen for: after the count-in, one chord per bar: E–F–G–E over C at 0:02, E–D–C over Am at about 0:05, C–D–E–F over F at 0:08 and a long D over G at 0:10; the loop comes round again from about 0:13. The tune never leaves five notes, C to G, right inside the ukulele’s band. That’s a good shape for a verse: easy to sing while you strum.

What to listen for: the same loop, but at 0:02 the tune jumps E–G–C and holds the high C, and over F at 0:08 it climbs to a high D. It now covers almost an octave, E to D, and it sits above the chords instead of among them. That lift is what a chorus needs. Write the verse like the first example and the chorus like this one, and the song has a shape.

If you play a tenor with a low G string (G3 instead of G4), you get a few notes below middle C for an intro line or a walking bass. For a full method on shaping a tune, see how to write a melody for a song.

Keys that suit your voice (and your fingers)

Choose the key by your voice, not by the shapes you like. Sing the melody’s lowest and highest notes, then enter them with your comfortable range in what key should I sing in. The link opens with a sample range of C3 to G4; change it to yours and the tool lists every key where the whole melody fits, best first.

Then pick shapes for that key. Some keys are kind to a ukulele player and some aren’t:

Key	I, IV, V and vi	Hard chord	Verdict
C	C, F, G, Am	None	Start here
G	G, C, D, Em	D (2 2 2 0, three fingers on one fret)	Easy
A minor	Am, Dm, E7, F	E7 (1 2 0 2)	The friendliest minor key
F	F, B♭, C, Dm	B♭ (3 2 1 1, a small barre)	Fine after a few weeks
D	D, G, A, Bm	Bm (4 2 2 2, barre)	Better with a capo
A	A, D, E, F♯m	E (awkward on ukulele)	Use G shapes with a capo on 2

To move a song you’ve already written, paste its chord sheet into the chord transposer and choose the new key. Set the capo fret yourself: the tool’s automatic capo suggestion counts the open shapes guitarists use, so it may steer you toward an E shape or away from an F that’s easy on the uke.

How to use a capo on ukulele

A capo clamps all four strings at one fret and becomes a new nut. Each fret raises the pitch a semitone and your shapes stay the same. Buy one made for ukulele: the neck is narrower than a guitar’s, and makers such as Shubb sell ukulele capos for soprano to baritone, for flat or curved fretboards.

Capo	C shapes sound in	G shapes sound in	F shapes sound in	Am shapes sound in
None	C	G	F	Am
1	D♭	A♭	G♭	B♭m
2	D	A	G	Bm
3	E♭	B♭	A♭	Cm
4	E	B	A	C♯m
5	F	C	B♭	Dm

Three limits to know:

• A capo only goes up. If C is too high, change family instead: G shapes with the capo on the 3rd fret sound in B♭, two semitones below C.
• Past the 5th fret the space gets tight. A soprano has 12 to 15 frets, so a capo high up leaves little room and a thinner sound.
• Retuning is another option. Some players tune the whole ukulele a whole step up, A D F♯ B (D tuning); a capo on the 2nd fret gives the same key without changing strings.

The same semitone logic works on guitar, so the capo chart is handy if you also play one.

Worked example: “Nobody Needs Me Till Nine”

The idea. The hour on the balcony before anyone needs you: coffee, a tin of basil, shirts drying, the street below waking up. One picture, one feeling, so the song stays small, like the instrument.

The loop and the strum. Verse: C–Am–F–G with four downs, quiet. Chorus: the same chords from F (F–G–C–Am) with the island strum, so it lifts by itself. Tempo 92 BPM. Hear the verse loop and the chorus loop.

The hum (10 minutes). Three recordings of “na-na” over four rounds of the verse loop. In the second one the verse tune stays low and close, between C and G like the stepwise example. Over the chorus loop the tune starts on A, above the chords, and climbs to a high D on the last word of the line.

The words. Speak the hummed rhythm, count the syllables per line in the syllable counter and fit real words with the same stresses. The verse lines run about 11 syllables; the chorus lines run 7, 10, 10, 7, so the chorus feels quicker even at the same tempo. For words that rhyme with “nine”, the rhyming dictionary gives line, mine, sign and shine; “line” also fits the picture.

Nobody Needs Me Till Nine
Tuning: G C E A · Key: C · Capo: none · 92 BPM
Verse: four downs · Chorus: island strum (D - D U - U D U)

[Verse 1]
C                       Am
Coffee on the railing, basil in a tin,
F                        G
below, the bakery lets the morning in.
C                       Am
Shirts along the wire, waving at the bus,
F                        G
the trumpet man upstairs hasn't noticed us.

[Chorus]
F                  G
Nobody needs me till nine,
C                        Am
four little strings and the shirts on the line,
F                      G
let the phone buzz on the table inside,
F        G          C
nobody needs me till nine.

Why it works. The title opens and closes the chorus, on the highest and the last note. The chorus starts on F, the IV chord, so the ear hears a lift before any word. The verse is a list of things you can see; the chorus says how they feel. And the last line ends on C, home, after three lines that end on G or Am.

The key. Sung in C, the melody runs from C4 to D5; a lower voice sings it an octave down, C3 to D4. If that D at the top strains, the vocal key tool will point lower, to B♭ or A: G shapes with the capo on the 3rd or 2nd fret (G–Em–C–D shapes). If it sounds dull, go up: C shapes with the capo on the 2nd fret put it in D.

A 30-minute ukulele songwriting exercise

1. Minutes 0–3: tune and choose. Tune G C E A with the tuner above and pick one loop from the table, in C.
2. Minutes 3–8: lock the strum. Play the loop with pattern A at 80 BPM until you can change chords without looking, then try pattern B.
3. Minutes 8–15: hum and record. Three hums over four rounds each, all recorded. Mark the best two bars.
4. Minutes 15–20: check the key. Sing the highest note of your best phrase. If it strains, go down a family of shapes; if it mumbles, use a capo.
5. Minutes 20–27: write words. One picture, one feeling. Speak the hummed rhythm, then fit words with the same stresses; title on the strongest note.
6. Minutes 27–30: one full take. Verse and chorus, uke and voice, on the phone. Write the header line before you stop.

Copy this sheet into your notes and fill it in as you go:

Record it the same day

You don’t need a studio, but you do need a recording you can find next week. Put the phone at about an arm’s length, pointing between the ukulele’s sound hole and your mouth, in the quietest room you have, and do one test take to check that neither the strum nor the voice covers the other. If you’re at a computer, the online voice recorder records in the browser and saves the file to your device.

Record twice: once with ukulele and voice, once humming the melody alone. The second take is the one you’ll thank yourself for, because the tune is clear when you can’t hear the chords. Name the files with the title, the section and the take, such as “Till Nine – chorus – take 3”. For more on getting a usable demo from a phone, see how to record demos with your phone.

Common mistakes and how to fix them

• The melody copies the top string. It fits, but it sounds like an exercise. Keep one note of it, then move the other way.
• The strum is busier than the words. If the line has a lot to say, drop to four downs or the off-beat pattern in the verse.
• Too many chords. Four shapes you can change without looking beat seven you can’t. Add a G7 or a Dm only when the song asks for it.
• The key comes from your fingers. Check the highest note against your voice before you write the second verse, not after.
• The capo and tuning get lost. Write “Tuning · Key · Capo · BPM” on the first line of the sheet. In six months you won’t remember the 2nd fret.

Where Zoundroom fits: the chords, the hummed tune and every take in one song

A ukulele song falls apart in a familiar way: the chords in a notebook on the balcony, the hums in the phone’s voice memos, the capo fret nowhere. In Zoundroom each song is a project with its recordings, lyrics, notes and files, so you can paste the chord sheet into the song’s note with its header line (“Tuning: G C E A · Key: C · Capo: none · 92 BPM”) and record the hummed chorus inside the note, right under the chorus lyrics; the audio is inserted at the cursor, next to the words it belongs to. Later takes, a version with the capo on the 2nd fret or a friend’s bass idea go into the same project, and you can share it with the people you write with. It works with the same account on iPhone, Android and the web app, which can also record in the browser. Two honest limits: Zoundroom doesn’t generate audio, has no virtual instruments or beats and isn’t where you mix and master the final track (a DAW such as GarageBand or BandLab is), and it has no tuner, so tune the ukulele with the free online tuner above. Your next step: open a new song, paste the sheet from the exercise and record the first take inside it.

Frequently asked questions

Is the ukulele good for writing songs? Yes, especially for a first song. The four basic shapes need one to three fingers, the instrument is quiet enough to play anywhere, and its small range keeps melodies simple and singable. What it lacks is bass, so the strumming hand has to carry the rhythm.

What are the easiest ukulele chords to write a song with? C (0 0 0 3), Am (2 0 0 0), F (2 0 1 0) and G (0 2 3 2). Together they make the I, vi, IV and V of C major, the base of countless songs. Add G7, Dm or E7 later for color.

How do I write a sad song on ukulele? Use the minor loop Am–Dm–E7–Am or start the four-chord loop on Am (Am–F–C–G), slow the tempo to 70–80 BPM and use the waltz or four soft downs instead of the island strum. The bright sound of the instrument against a sad lyric can be very moving.

Do soprano, concert and tenor ukuleles need different chords? No. All three are tuned G C E A, so the shapes are the same; the tenor’s longer neck gives a fuller sound and more room for a capo. Only the baritone, tuned D G B E, changes the chord names.

Can I sing in a low voice over a ukulele? Yes. A lower voice sings the melody an octave below the ukulele’s chords, which sounds natural. Choose the key by your range with the vocal key tool, not by where the uke sounds.
