Frequently Asked Questions About Key & BPM Finder
Everything you need to know about finding the key, BPM, and Camelot value of your music.

Upload any song, and our tool reveals this data instantly—perfect for DJs creating seamless mixes, producers matching samples, or musicians learning new tracks.
What is Alt Key (Camelot Wheel)?
The Camelot Wheel is a DJ tool that assigns each musical key a number and letter (like 8A for A minor or 8B for C major). Keys next to each other on the wheel mix harmonically without clashing.
