Virtual Ukulele: Play Strings, Notes and Chords
Play a virtual ukulele with four strings, twelve frets and real recorded ukulele sounds. Choose a chord, strum down or up, or pick individual notes on the fretboard. You can switch between high-G and low-G tuning and hear how the same chord shape changes. The tool is free, works in your browser and does not need a microphone or an account.
Play your first ukulele chord
Press Enable ukulele sound once to load the recordings. Choose C above the fretboard, then press Down strum. The four strings sound in sequence, just as a downstroke crosses them on a ukulele. Press Up strum to reverse that order. Selecting an unfamiliar chord is silent, so you can inspect its shape before playing it.
The gold markers show the selected fret on each string. A marker in the Open column means that string is played without pressing a fret. Tap another position to change one string and hear its new note immediately. The selected positions remain in place for the next strum; you can therefore build your own four-note combination rather than being restricted to the preset chords.
For a simple first comparison, alternate C and Am. Listen once to the whole chord, then use keys 1, 2, 3 and 4 to pick its strings separately. Those keys follow G, C, E and A, in that order. After enabling sound, the shortcuts work anywhere on the page unless you are changing a form control. D plays a downstroke, U plays an upstroke, and Escape stops the sound.
On a phone, the neck shows six positions at a time so the notes remain large enough to touch. Use the 6–12 button to reach the upper frets, then return to 0–5 for open-position chords. You do not need to turn your phone sideways. The note-name switch hides unselected note labels if you prefer a cleaner view, while the selected positions remain visible.
Understand the four strings before learning shapes
This ukulele uses G–C–E–A tuning. In the default high-G setting, the open strings are G4, C4, E4 and A4. The number identifies the octave: C4 is middle C, while C5 is an octave above it. A string name without an octave is useful for remembering the tuning, but it does not fully describe how high that string sounds.
The horizontal neck uses the same vertical string order as ukulele tablature: A is the top row, followed by E, C and G. This is a diagram convention, not an instruction to turn your real instrument upside down. Chord-shape numbers on this page are written in the opposite reading direction, G–C–E–A, and are labelled explicitly. Keeping those two conventions separate prevents many beginner mistakes.
The open C string is the lowest note in high-G tuning, even though G is listed first. Play the open strings slowly: G4 to C4 drops in pitch, C4 to E4 rises, and E4 to A4 rises again. Do not treat the four open strings as an ascending scale. This return to a higher note on the G string is the reason the tuning is described as re-entrant.
Try finding the same pitch in two places. The fifth fret of the E string and the open A string both produce A4. The seventh fret of the C string produces G4, matching the open high-G string. The written pitch is the same; a physical instrument may give each position a slightly different colour. This browser version uses pitch-based samples and does not reproduce every string-specific timbre.

| String | High G | Low G | Keyboard |
|---|---|---|---|
| 4 · G | G4 | G3 | 1 |
| 3 · C | C4 | C4 | 2 |
| 2 · E | E4 | E4 | 3 |
| 1 · A | A4 | A4 | 4 |
Six useful ukulele chords and what their numbers mean
A shape such as 0–0–0–3 gives one fret number for each string in G–C–E–A order. It means open G, open C, open E, and the third fret of A. These numbers are fret positions, not finger numbers. You will hear G4, C4, E4 and C5 in high-G tuning: four sounding strings, but only three different note names, C, E and G. That is a C major chord.
Start with C, Am and F before adding G. In C, only the A string is fretted. In Am, only the G string is fretted. Moving from Am to F keeps the second fret of G and adds the first fret of E. That shared position makes the change easy to understand visually. On a real ukulele, practising a shared finger position can also reduce unnecessary movement.

| Chord | Frets | Chord tones |
|---|---|---|
| C major | 0–0–0–3 | C, E, G |
| A minor · Am | 2–0–0–0 | A, C, E |
| F major | 2–0–1–0 | F, A, C |
| G major | 0–2–3–2 | G, B, D |
| G seventh · G7 | 0–2–1–2 | G, B, D, F |
| D minor · Dm | 2–2–1–0 | D, F, A |
To check a chord, pick all four strings separately before strumming. In F, for example, you hear A4, C4, F4 and A4. The doubled A is expected; a four-string chord does not need four different note names. Compare G with G7 next. Only the E-string position changes from fret 3 to fret 1, introducing F instead of G and creating a different harmonic pull.
The C–Am–F–G example is an original practice sequence, not a recording of a named song. It plays each chord once and stops. After listening, recreate the changes manually. If you are learning with a physical instrument, use the diagrams to check your frets, then judge your own sound string by string. The virtual tool cannot tell whether your fingers are muting a real string.
High G or low G: hear the difference
Switch to Low G and play the open strings again. Only the G string changes: G4 becomes G3, one octave lower. C4, E4 and A4 remain unchanged. The open strings now rise steadily in pitch from G to A. This makes it easier to hear a low-to-high line and extends the available melody range downward.
The same fret numbers still form the same named chords because an octave change preserves the note name. Their voicing is different, however. C major becomes G3–C4–E4–C5 with the shape 0–0–0–3, placing G underneath C. It is still a C chord, but the lowest sounding note is G rather than C. A chord’s name and its bass note are not always identical.

To compare fairly, keep the volume and chord shape unchanged while switching tuning. Try C, then F, then a single open G. Notice the lower weight in low-G tuning and the more tightly grouped pitches in high-G tuning. Neither setting is a quality upgrade; they provide different ranges and arrangements.
The real recordings used here begin at C4. The low-G notes below that range are made by lowering the pitch of the nearest recording. They demonstrate the correct pitch relationship but are not dedicated recordings of a low-G string. On a physical ukulele, changing from high G to low G generally requires a suitable string and attention to the instrument’s setup; do not treat this switch as advice to retune any existing string arbitrarily.
Explore the fretboard without memorising everything
Each fret raises a string by one semitone. Starting from the open C string, the first fret is C♯4, the second D4, the third D♯4 and the fourth E4. The tool displays sharps for consistency. In another musical context, the same sounding pitches may be written as D♭ or E♭. The spelling changes, but the location on this equal-tempered virtual fretboard does not.
Use the twelfth fret as an anchor: it is one octave above the open string. Open A is A4 and its twelfth fret is A5. The same relationship holds for all four strings, including G3 to G4 in low-G tuning. The upper-fret selector changes which positions are visible; it does not transpose the tuning or erase your selected notes.

A manageable first melody exercise is the first five notes of C major on the C string: frets 0–2–4–5–7, producing C–D–E–F–G. Play upward, pause, then return 7–5–4–2–0. Keep each note equally spaced. The movement from E to F is one fret; the other adjacent moves in this five-note pattern are two frets. That is a useful way to hear the distinction between a semitone and a whole tone.
Once that feels familiar, find E4 on both the open E string and the fourth fret of C. Build a short answer to your first phrase using those two locations. You are learning the relationship between sound and position, not simply following lights. For a visual comparison, open the virtual piano and locate the same note names. The pitch relationships remain the same even though the layout changes.
Make a chord progression sound musical
A chord list does not specify a rhythm. Start by counting one, two, three, four and playing one downstroke on each count. Stay on C for four counts, then move to Am for four. Add F and G only when the first change feels controlled. If you are practising on a real instrument, a slightly slower tempo with clean changes is more useful than a fast tempo full of pauses.
For a second exercise, count one-and-two-and-three-and-four-and. Play a downstroke on each number and an upstroke on each “and”. The browser’s down and up controls reverse the order in which the strings start; they are not separate recordings of every possible hand movement. This is enough to compare the direction and spacing of strokes, but it does not teach the physical contact of fingers against strings.

Use the online metronome to set a steady reference, perhaps 60 BPM as a comfortable starting experiment rather than a required training speed. If a chord change causes you to miss the next beat, keep the pulse going and simplify the pattern. Play one stroke per bar, make the change, then gradually add strokes back.
You can also pick an arpeggio: choose C, then press 1–2–3–4 at equal intervals. Repeat in reverse. Because high-G tuning is re-entrant, the first pattern does not necessarily rise in pitch. Say the note names as you play, then try predicting whether the next sound will be higher or lower. The interval ear-training exercise offers a separate way to practise listening between two pitches.
A focused ten-minute practice session
Spend the first two minutes checking the four open strings. Name each one before playing it, and identify the lowest pitch without looking at the diagram. Switch tuning once and explain what changed. If you can only remember the letters but cannot predict the pitch direction, repeat the listening comparison instead of adding more notes.
Use the next three minutes for C, Am and F. Select each shape, pick its four notes and strum it once. Your goal is to understand which string changes between shapes. With a physical ukulele, leave a shared finger in place where practical and release unnecessary pressure. With the browser tool, use the highlighted positions to make the same relationship visible.
For the following three minutes, play the five-note C-string pattern from the fretboard section, then its reverse. Work at an even pace. Finish with two minutes of C–Am–F–G, one chord per four counts. Record your observations on paper: which change interrupted the pulse, which string was hard to identify, and what you want to repeat next time.
This is a practice outline, not a promise of progress in a fixed number of days. The web instrument helps with pitch, chord shape and short comparisons; regular listening and physical playing develop other skills. For separate, structured ear-training work, KulakApp provides the next step through its mobile app rather than turning this single page into a full course.
Read a short ukulele tab without confusing strings and frets
Ukulele tablature gives positions rather than conventional staff notes. Each horizontal line represents a string, with A at the top and G at the bottom. A number tells you which fret to play on that line. A zero means the open string. Read events from left to right; numbers directly above one another belong to the same moment. A simple tab without rhythm markings does not tell you exactly how long each note lasts.
For example, a 3 on the A line means the third fret of the A string, which is C5 in this tuning. It does not mean the third string, the third finger or the third beat. To test your reading, select that position on the virtual neck, then find the same note name elsewhere. The eighth fret of E also gives C5, while the twelfth fret of C reaches C5 by a different route.
Try this original phrase on the A string: 0, 2, 3, 2, 0. It gives A4, B4, C5, B4, A4. Start with one note per count. On the second repetition, hold the final A for two counts. Nothing about the fret sequence changed, but the ending now breathes differently. That small experiment separates pitch choice from rhythm, two decisions that are easily confused when following a busy diagram.
Next, move to the E string and play frets 0, 1, 3, 1, 0. You hear E4, F4, G4, F4, E4. Compare the opening step with the A-string phrase. A to B is a whole tone; E to F is a semitone. Similar-looking five-note patterns can therefore have different internal spacing. The fret numbers make that difference visible without needing to memorise an entire scale chart.
When returning to a physical instrument, check the tuning before using a tab. A tab written for G–C–E–A assumes those open-string pitches. The same fret numbers on a differently tuned instrument will not give the same notes. High and low G also change the octave of anything on the G line. This tool helps check the resulting sound, but it does not supply the missing rhythm of a tab you found elsewhere.
Check what you heard, not how fast you clicked
Give yourself one small question at a time. Which open string is lowest in high-G tuning? Which single position changes between Am and F? Which two strings can produce A4 without using an upper fret? Answer before touching the instrument, then use it to check. A correct guess is less useful than being able to explain the relationship after hearing it.
If a chord sounds unfamiliar, do not immediately assume the tool or the shape is wrong. Check the tuning selector, the four displayed fret numbers and the selected pitches. A custom note remains selected until you choose another shape or reset to open strings. Picking an upper fret on one string can therefore change the next strum even after you return to the lower part of the neck.
For a listening comparison, change only one thing at a time. Keep the same chord while switching high and low G, or keep the tuning while switching G and G7. If you also change the volume, stroke direction and tempo, it becomes harder to identify what caused the difference. This habit is useful beyond ukulele: a controlled comparison makes unfamiliar musical ideas easier to hear.
There is no score attached to these experiments. Take a break when you start clicking without listening, and return to one clear question. The aim is a usable connection between the diagram and the sound, not a high number of taps or a claim that one short browser session proves your ability.
About the sound and quick troubleshooting
The sound bank contains actual tenor ukulele notes recorded by Mateusz Dąbrowski and distributed by FreePats under CC0. The browser selects a nearby recording and changes its playback rate for notes between sampled pitches. The source tuning corrections are retained. This is sampled audio, not the simple oscillator tone used in the earlier version of this tool.
The recordings load after you enable sound, then stay in memory while this page is open. Playing another note does not download it again. The natural decay is preserved, and each string’s previous note is gently stopped when you play a new note on that string. A volume control and output compression help keep a strum manageable, but you should still begin at a comfortable device volume.
If there is no sound, confirm that the loading message has changed to Ready, raise the tool’s volume slightly and check the tab and device output. A failed download shows a retry option. If the page has been in the background, tap a control again to resume audio. The tool never asks for microphone access because it plays reference sounds rather than analysing your instrument.
If you hear a delay, compare the device speaker or wired headphones with Bluetooth headphones. Wireless output can add audible latency even when the browser starts the note promptly. Close unusually heavy background tabs and try a current browser. The first sample download is a one-time loading step, not the expected delay between every tap and note.
A virtual fretboard cannot reproduce string tension, finger pressure, buzzing, muting technique or the feel of a strum. It is useful for hearing ideas before playing them physically. It should not be presented as a microphone tuner, a recording studio or an automatic measure of musical ability.
Virtual ukulele questions
Is this virtual ukulele free?
Yes. You can load the sounds, play all twelve frets and use the chord presets without signing in. No microphone permission or payment is required for this web tool.
Can I play ukulele chords on my phone?
Yes. Choose a chord and tap Down strum or Up strum. The fretboard uses two position ranges to keep the touch targets usable on a narrow screen. You can change individual string positions as well.
Are these real ukulele sounds?
The source notes are real tenor ukulele recordings released under CC0. Pitches between the recorded notes are produced by playback-rate changes. Low G below C4 is pitch-shifted, not a separately recorded low-G string.
Can I use it to tune a real ukulele?
You can compare your strings with the open reference notes by ear. The page does not listen to your instrument or indicate whether a real string is sharp or flat. Use a suitable tuner for measured tuning.
Does it support baritone ukulele tuning?
No. This version uses G–C–E–A with high or low G. Do not use its chord shapes as a baritone D–G–B–E chart without accounting for the different tuning.
Why does G sound higher than C?
In high-G tuning, G4 is above C4. That is intentional. Switch to Low G to hear G3 below C4 while the other three strings stay unchanged.
Why does selecting a chord not play it immediately?
Selection lets you inspect the shape without unexpected audio. Use the strum buttons or pick individual strings to hear it. The four-chord example is a separate, explicitly started playback.
Can I save or record a performance?
This version does not record, export audio or upload your playing. It is a short practice tool. A new page load resets the selected frets and tuning.
