Draw a random guitar chord from 118 real voicings in standard tuning, each with a proper chord box showing frets, fingering, and which strings to leave out.
A chord box is the fretboard seen head-on: the six vertical lines are the strings, low E on the left, and the horizontal lines are the frets. A thick bar across the top is the nut, meaning the shape sits at the first fret; a number beside the box instead means the diagram starts further up the neck. Dots show where fingers press, numbered 1 to 4 from index to little finger, and a long rounded bar is one finger flattened across several strings. Above the box, an o marks a string played open and an x one you don't sound at all.
This generator draws from 118 real chord voicings in standard tuning, across Open Chords, Barre Chords, Seventh & Jazz Voicings, Extended & Altered, and Power & Movable Shapes. Every draw comes with a proper chord box -- fret positions, fingering, open and muted strings, and the bass note the voicing actually sounds. The movable shapes are expanded from a single template across roots, so a barre form is correct by construction rather than by transcription.
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
Practise by drawing a chord and finding it without looking anything up, build a random progression by drawing four in a row, break out of the five shapes you always use, or learn the movable forms by seeing the same shape land on different roots. Filter to Extended & Altered when the open chords have stopped teaching you anything.
Generate draws one voicing at random using the site's cryptographically secure randomness, never repeating the chord currently shown in single-result mode, and renders it as a standard chord box. Every voicing in the pool is checked against its own name by a script that works out the pitch classes it sounds and compares them to the chord the name claims -- so a fret typed one off fails the build rather than shipping.
A sample of what this generator can draw, spread evenly across the full list:
Standard tuning, E A D G B e, low to high. Nothing here assumes a capo, drop tuning, or a seven-string.
Which finger to use: 1 is the index, 2 the middle, 3 the ring, 4 the little finger. They're a strong suggestion rather than a law -- experienced players often re-finger a shape to make the next chord easier to reach.
That's the fret the top of the box represents. Without it, a barre chord at the eighth fret would look identical to one at the first, which is the single most common way of learning a chord in the wrong place.
