Each diagram shows the ukulele fretboard from the nut (top) down. Vertical lines represent the four strings (G-C-E-A in standard tuning), and horizontal lines represent the frets. Filled dots show where to place your fingers, while open circles above the nut mean that string is played open (unfretted). The thick bar at the top represents the nut; if it's absent, a number indicates the starting fret position.

Essential Chords for Beginners

Start with C, Am, F, and G — these four chords let you play hundreds of popular songs. C major is the easiest: just one finger on the first fret of the A string. Am uses the same shape on a different string. Once comfortable, add Em, D, and A to your repertoire. The "Popular" tab above shows the most commonly used chords.

Understanding Chord Voicings

Many chords have multiple voicings — different finger positions that produce the same chord. For example, C major can be played as a single note on the third fret of the A string, or as a full barre chord higher up the neck. Use the arrow buttons below each diagram to cycle through available voicings. Different voicings suit different musical contexts and can make chord transitions smoother.

Chord Types Explained

Major chords sound happy and bright — they're built from the root, major third, and perfect fifth. Minor chords sound sad or serious, lowering the third by a half step. Seventh chords add a fourth note for jazzy richness. Diminished and augmented chords create tension and surprise. Sus chords (suspended) replace the third with a second or fourth for an unresolved, dreamy quality.

Tips for Clean Chord Changes

Practice switching between two chords slowly until the movement feels natural, then gradually increase speed. Look for common fingers — notes that stay in the same position between chords become anchor points. Lift all fingers simultaneously rather than one at a time. Use the minimum pressure needed to get a clean sound; pressing too hard causes fatigue and slows transitions.

Alternate Tunings

This chord library supports multiple tunings. Standard gCEA works for soprano, concert, and tenor ukuleles. Low G tuning extends the bass range for fingerpicking. Baritone DGBE uses the same chord shapes as the top four guitar strings. D-tuning and slack-key tuning offer unique Hawaiian voicings. Use the tuning selector above to switch — all chord diagrams update automatically. Need to tune up first? Use our free ukulele tuner. Once you know your chords, explore ukulele scales to start improvising, and practice your timing with the metronome.
