Chord diagramsScale diagram
How each diagram is drawn and annotated
Replaces double accidentals with their enharmonic equivalent — the same pitch, a simpler name. They turn up because every scale degree takes its own letter.
Draws every string in the colours of the Aquila Kids educational ukulele set — green (G), red (C), yellow (E) and blue (A). On other instruments and tunings the colours follow the string positions.
7add9, 6add9 and maj7add9 always drop their 5th to fit these 4-string instruments. A 7th, 6th or add9 chord drops its 5th too when a slash bass outside the chord (like E7/A) would otherwise push it to 5 notes. When on, affected chords show a note naming the dropped tone.
Crop above fret5
Diagrams normally start at the nut. If a chord's lowest fretted note is above this fret, the diagram is cropped to a short window at the chord's position instead. Example — a chord played entirely at fret 5:
Voicing search
Which fingerings the search may offer, on every chord
Search up to fret
Highest fret considered when searching for voicings. Raise it to unlock higher positions and more alternatives. Applies to every chord on the sheet and to the voicing chooser, which carries the same three controls.
Max stretch
Widest stretch a fingering may cover, counted in frets from its lowest to its highest fretted note — voicings needing a wider reach are discarded. Lower it if a shape asks for more reach than your hand has.
Lets chords with only two notes (power chords) or three notes skip strings — drawn × above the nut — instead of doubling a note onto them. Often an easier grip; the sound is thinner.
Playback
How chords sound when you hit ▶
Plays the notes of a chord one after another, like a slow fingerpicked roll, instead of a quick strum. Bass guitar chords always play arpeggiated — strummed together, notes that low blur into a rumble.
Show
Packs tiles into columns by height instead of aligning them in even rows. This only makes a visible difference when tiles have different heights — with equal-height tiles both layouts look the same.
Tap a fret to place a note. Tap the ○ or × above a string to sound it open or mute it.

Find songs with these chords
Also finds songs that use the same chord pattern in another key: C, Am, F, G shifted 5 semitones down becomes G, Em, C, D — the chords of Dandelions by Ruth B., which matches with a “−5 semitones” badge. The chords listed are always the song's own.
