Free Chord Finder

Free chord finder: drop your own recording to see its chord progression across the bars, with the key and tempo. Veena gives your next song a harmonic direction, then CoProducer builds the parts with you as editable tracks.

Veena is an AI DAW with a personal music producer built in. Describe the song you want and CoProducer builds it with you — beats, chords, melody, arrangement and mix — as real tracks you can edit, mix and export. Free, in your browser.

How to use the chord finder

1. Choose your recording. Drop a demo, guitar take, piano loop or voice memo into the tool, or press Choose audio file.
2. Read the progression. The results show the key, tempo and chord changes across the beat and bar grid. Follow a whole phrase to see where it returns to its first chord.
3. Hear your recording. Play the local audio while following the grid. Notice where a verse repeats the same harmony or a chorus changes the direction.
4. Build on the chords. Select Build a track on these chords with CoProducer. The button copies the musical brief and opens Veena with it ready to send.
5. Direct the band. Add a genre, instrument and feel to the brief. Ask for a bassline on the roots, a melody over the changes and drums that support the phrase.

For a familiar four-bar pop phrase, C–G–Am–F gives you home, lift, a minor turn and a route back to C. Name that progression in your request and say how long each chord should last. CoProducer can put it on piano, strings or a synth, then develop the arrangement around it.

Chord changes laid out over the bars

A chord name tells you which notes sound together. A progression tells you how those chords move through time. The grid connects both: each reading has a place in the beat and bar count, so a two-bar chord and a quick change occupy different amounts of musical space.

Use the key to give the progression a tonal centre. In C major, C–G–Am–F is I–V–vi–IV. In B-flat major, Cm–F–B-flat is ii–V–I. Those numerals describe the relationship between the chords; their names tell you the notes to play in that key.

When you take the progression into Veena, describe the rhythm too. "One chord per bar" gives a different part from "short stabs on the offbeats". The same harmony can become a pop piano part, a house organ pattern or a spacious string arrangement. CoProducer uses your direction to build the sound and phrasing.

Keep your recording on your device

The chord finder runs entirely in your browser. It prepares a bounded audio excerpt using the same reader as the key and BPM finder, then a worker reads the beat-aligned harmony. The recording is analyzed locally, with no upload and no paid analysis API.

The chord brief travels to Veena as text. Your recording stays in the finder. If you want CoProducer to build around your take, import the audio into your Veena project and describe the parts you want beside it. Your voice memo or guitar phrase becomes one track in an arrangement you can keep producing.

Start a new song on the progression

The AI chord progression generator is the harmony hub for CoProducer: describe exact chord names, a mood or a genre, and build the music as MIDI tracks. For a progression you can hear and change on this page's sister tool, use the playable chord progression generator.

Keep the phrase concrete. Name the progression, tempo and instrument, then ask for the next musical job. A bassline can follow the roots and leave room for the kick. A melody can repeat a short hook over two different chords. The drums can mark the chorus while the chords stay the same.

Try this in Veena:

Build a 16-bar pop song at 120 BPM in C major on C, G, Am and F, one bar each. Play the chords on piano, add a warm bassline and a tight drum groove, then develop a verse and chorus.
