Key, tempo and structure, explained
Built for people who work with songs
“Key and Camelot in one drop, then I check the BPM, it's faster than loading a track into my library software just to see if two songs mix. The harmonic codes are spot on.”
Andre Costa
Club DJ
“The structure map is the part I didn't know I needed. Seeing exactly where the chorus and bridge hit lets me lay out an arrangement in minutes instead of scrubbing the waveform.”
Mei Lin
Music producer
“I edit music videos, and cutting to the section drops used to mean counting by ear. Now I get the chorus timestamps and the beat grid and the edit just lands.”
Tom Becker
Video editor
Song Analyzer FAQ
- What is a song analyzer?
- A song analyzer reads musical information from an audio file. This one detects the key, Camelot code and tempo (BPM) in your browser, and can map the song's structure into sections like verse, chorus and bridge.
- Is it free?
- Key, Camelot and BPM detection are completely free with no sign-up and run right in your browser. The deeper structure analysis is an optional step for signed-in users.
- How accurate is the key detection?
- Key detection is a strong estimate, relative major and minor keys share the same notes and can read either way. Use it as a reliable starting point and trust your ears for the final call.
- What is the Camelot code for?
- The Camelot code makes harmonic mixing easy: tracks with the same code, or one number apart on the wheel, mix in key. DJs use it to build smooth, in-key transitions.
- What does structure analysis show?
- It splits the song into labeled sections, intro, verse, chorus, bridge, outro, on a timeline, along with the tempo, beats and downbeats, so you can see exactly where each part begins.
- What audio files can I analyze?
- Common formats including MP3, WAV, M4A, FLAC and OGG. For key and BPM the file is read locally in your browser; nothing is uploaded for that step.
- Does it work on any genre?
- Yes, pop, rock, electronic, hip-hop and more. Strong, steady beats give the most confident tempo and structure results; very free-time or ambient music is harder to read.
