How to Find the Key and BPM of a Song in Ableton Live
You have a song in your Ableton Live set and you want to know its key and its BPM. The BPM part is mostly built in. The key part usually is not. Here are the ways to get both, and how to check that you can trust them.
BPM: let Live guess, then check it
Drop the audio onto an audio track. With Warp on, Live analyses the clip and sets a tempo. To check it:
- Play the clip with the metronome on.
- Listen for the click landing on the kick across the whole song, not just the first bar.
- Look at the warp markers. If they sit on the transients, the grid is right.
If the tempo seems to be half or double, use the 2x or /2 buttons on the clip. Songs without a steady click, such as live recordings, may drift. Fix the markers by hand where it moves. See BPM vs tempo if the two terms confuse you.
Key: Live does not tell you
Live helps you work in a key, but it does not analyse an audio clip and name its key. You have these options:
- Your ears. Play a keyboard along with the loop and find the note that feels like home. Our guide to finding the key of a song walks through it.
- A Max for Live device. Key & BPM Finder is ours: you drop a track onto it inside your session and it shows the key, the relative key and the BPM. It is $14.99 and works in Live only.
- Another app. Mixed In Key, KeyFinder (free) and DJ software such as rekordbox and Serato all analyse files. You then carry the answer back to Live.
- A lookup site. Fine for a released song, useless for your own bounce.
See Tunebat alternatives for how these compare.
Use the Camelot code
Once you have the key, write it down as a Camelot code (for example 8A for A minor). The Camelot wheel shows you which keys sit next to it, which is what you need when you pick samples and layers.
Checks that catch most errors
- Half or double time. 70 and 140 can both be correct.
- Relative major and minor. A minor and C major share notes. Play the root and listen.
- A change of key. If the song modulates, check the section you will use.
When you want the song itself in the set
If you also need the audio, not just the numbers, Premix does the whole step: type a song, it picks the official audio, reads the key (with the Camelot code) and the BPM, and in Live 12 puts the song on its own track on the grid and can set your project''s tempo and key to match. It can also split stems and import a file of your own. $39 one-time, Mac and Windows, 14-day money-back guarantee, for your own sessions and practice.
