Tools

BPM and key of an audio file

analyze_audio_file

What it does:
Measures the tempo, musical key, Camelot code, energy, danceability and loudness of a song, and lists the keys that mix well with it.
Give it:
A direct public https link to the audio file. MP3, WAV, M4A, FLAC, OGG and Opus files up to 60 MB and 12 minutes. Songs longer than four minutes are measured over their middle four minutes.
In apps that show cards:
A card with the BPM, key and Camelot code, and tabs for the song's chords and a metronome at its tempo.

Chords and notes of any key

get_key_info

What it does:
Gives the notes, chords, seventh chords, common progressions, key signature, relative key and Camelot code of any major or minor key, and the keys that mix well with it.
Give it:
A key name such as "F# minor", "Bb major" or "Am", or a Camelot code such as "11A".
In apps that show cards:
A circle of fifths and the key's chords, which you can play.

Delay times and feel of any tempo

get_tempo_info

What it does:
Gives delay and echo times in milliseconds, half time and double time, the Italian tempo marking, the length of a bar and the genres usually played at that tempo.
Give it:
A tempo from 20 to 300 BPM.
In apps that show cards:
A metronome you can play and tap along with.

All three tools only read: they never change anything, and nothing is saved to an account.

Things to ask

  • What's the BPM and key of this song? https://example.com/my-song.mp3
  • What are the chords in F sharp minor, and which keys mix well with it?
  • What delay time should I use at 128 BPM?
  • Which keys can I mix into from Camelot 8A?
  • What's half time for 174 BPM, and which genres use that tempo?

Claude can't pass a file attached to the chat to these tools, so share a direct link to the audio file instead, such as a link that ends in .mp3.

Privacy

  • No account or sign-in. The tools never see your name, email or chat history.
  • Audio files are downloaded, measured in memory and then discarded. They aren't saved, and they aren't used to train anything.
  • Key and tempo questions are answered and not stored.
  • Your network address is used only to apply rate limits, and those counts expire within a day. See section 13 of the Privacy Policy.

Limits and troubleshooting

  • Up to 20 audio files an hour per person.
  • If a link can't be read, check that it opens the audio file itself, not a page about it, and that it doesn't need a login. Links to private network addresses are refused.
  • Some songs read at half or double the tempo you would count by ear, so the answer gives half and double time too.
