FindTheChords is a free online chord finder that uses audio analysis to detect the key, BPM, and complete chord progression of any song. Whether you're a guitarist learning a new track, a pianist working out harmonies, or a producer analyzing a reference track, our tool gives you accurate results in seconds.
Upload any audio file — MP3, WAV, AIFF, or M4A — and our analysis engine processes the audio signal to extract harmonic information. The algorithm identifies individual chords by analyzing frequency content across the audio spectrum, then maps them to standard chord names with precise timestamps. You can also paste a YouTube URL and we'll extract the audio directly for you.
Musicians of all skill levels use FindTheChords. Beginner guitarists use it to learn songs by ear faster. Session musicians use it to quickly chart songs for gigs. Music teachers use it as a teaching aid for ear training. Worship leaders use it to prepare chord charts for their teams. Producers and DJs use it to identify chord progressions in reference tracks for sampling and remixing.
Every chord in the song identified and labeled with precise timestamps. Follow along in real time as the song plays, or export the full chart to practice later.
Instantly know what key the song is in. Essential for transposing to your vocal range, choosing the right capo position, or finding compatible songs to mix.
Get the exact tempo so you can set your metronome, match the tempo in your DAW, or find songs at a similar BPM for DJ sets and playlists.
Instead of searching through inaccurate chord tabs online, upload the actual recording and get the real chords. Our chord detection analyzes the original audio, so you're learning the correct progression — not someone's guess. This is especially useful for songs that don't have accurate tabs available, like newer releases, independent artists, or live recordings with unique arrangements.
Worship leaders and band leaders need chord charts quickly, often for songs they've just heard. Upload the audio, get the chords with timestamps, and you have a working chart ready for rehearsal. Combine the key detection with a capo chart to find the most comfortable key for your vocalists. This workflow saves hours of manual transcription every week.
Producers and songwriters often study the chord progressions of hit songs for inspiration. Upload a reference track to see its full harmonic structure broken down with timestamps. Identify common progressions like the I-V-vi-IV pop formula, see how songs use key changes, and understand why certain progressions create specific emotional responses. The BPM detection helps you match tempos when building beats.
Music students and self-taught musicians can use FindTheChords as an ear training companion. Try to identify the chords yourself first, then upload the audio to check your work. Over time, you'll build the ability to recognize chord qualities (major, minor, seventh) and common progressions by ear — one of the most valuable skills a musician can develop.

Everything you need to know about finding chords
Our chord finder uses advanced AI and audio analysis algorithms to detect the harmonic content of your audio file. Simply upload an MP3, WAV, AIFF, or M4A file, and our system analyzes the frequencies to identify chords, key, and BPM within seconds. The process is completely automatic and requires no musical knowledge.
Yes! FindTheChords is 100% free with no hidden fees, subscriptions, or signup required. You can upload unlimited songs and get complete chord progressions, key detection, and BPM analysis without paying anything. We're committed to keeping this tool free forever for all musicians.
We support MP3, WAV, AIFF, and M4A audio files up to 50MB in size. These formats cover virtually all music files you'll encounter. For best results, use high-quality audio files (320kbps MP3 or WAV files).
Our chord detection achieves 95%+ accuracy on popular music genres including pop, rock, country, R&B, and hip-hop. Accuracy may vary with complex jazz harmonies, heavily distorted music, or songs with multiple instruments playing different chords simultaneously. We recommend verifying results by ear for critical applications.
Absolutely! FindTheChords works for all instruments. The chord progressions we detect are universal and can be played on guitar, piano, ukulele, bass, or any other instrument. The key and BPM information helps you tune your instrument and play along at the correct tempo.
No account needed! You can use FindTheChords immediately without any signup, registration, or login. We don't collect personal information or require email addresses. Just visit the site, upload your file, and get instant results.
Most songs are analyzed in 10-30 seconds, depending on the file size and length. Shorter songs (under 3 minutes) typically process in 10-15 seconds, while longer tracks may take up to 30 seconds. The analysis happens entirely in your browser for maximum speed.
Currently, you need to upload an audio file directly. However, you can download audio from YouTube using third-party tools (ensuring you have proper permissions), then upload the file to FindTheChords for chord detection.
The 'key' tells you the overall tonality of the song (like C major or A minor), which determines which notes and chords will sound good together. 'Chord detection' identifies the specific sequence of chords throughout the song with timestamps. We provide both: the overall key plus the complete chord progression with timing.
Yes! You can download your chord chart as a PDF or text file. The results include the song key, BPM, and complete chord progression with timestamps so you can practice, share with bandmates, or save for later reference.
