Analyze a song insteadUpload audio to detect chord changes across a song.A chord finder identifies possible chord names from the notes you select. Use the chromatic note picker, piano layout, or guitar fretboard when you know the sound or fingering but not the chord name.
Select pitch classes and compare the most likely chord names immediately.
Mark one fret on each string and identify the harmony created by that shape.
Play the active notes together before opening a related guitar diagram.
See alternative names when the same notes can be interpreted with another root or inversion.
Use Notes, Piano, or Guitar according to the information you already have.
Select at least three different notes or mark the played fret on each guitar string.
Compare the first result with alternative roots and chord spellings.
Play the voicing, then open a matching guitar chord page when one is available.
Identify a chord discovered while experimenting on the fretboard.
Select the keys in a voicing to find the chord and possible inversion names.
Confirm that the notes played by several instruments form the intended harmony.
Compare roots, thirds, fifths, sevenths, and altered tones by changing one note at a time.
Select every different pitch in the chord. The finder compares that pitch-class set with common chord formulas and returns possible names.
The same collection of notes can represent an inversion, an omitted tone, or a chord with a different root depending on musical context.
Yes. Choose one fret or an open string for each sounding string, mute unused strings, and review the detected names.
The chord identity uses pitch classes, but the lowest note can change the inversion and therefore the displayed slash-chord interpretation.
The strongest results come from three or more different notes. Two-note shapes are often ambiguous because they omit the third that distinguishes major from minor.
Find BPM from a song, loop, or recording, review confidence, and compare half-time or double-time readings.
Analyze a song, loop, acapella, instrumental, or recording locally, then review confidence and compatible keys.
Detect chord changes, review a synchronized timeline, correct labels, and export a TXT or CSV chord chart.
Select notes or mark a guitar shape, hear the voicing, and compare likely chord names.
Search common major, minor, seventh, and major seventh shapes, hear them, and open detailed references.
Compare chord diagrams by root, quality, and difficulty, then open a detailed reference or print the chart.
