Is Track Finder a song-recognition app like Shazam?

No. Track Finder does not identify a song from a recording. It answers the opposite question: given a key and tempo, which tracks will mix with it harmonically. Song-recognition services such as Shazam, AHA Music or SongFinder solve a different problem.

How does harmonic mixing with the Camelot wheel work?

The Camelot wheel labels the 24 musical keys 1A–12A (minor) and 1B–12B (major). Tracks mix cleanly when their codes are the same, one step apart on the number (8A → 7A or 9A), or share the number with the other letter (8A → 8B). Moving +2 on the number (8A → 10A) is the energy-boost mix. Track Finder applies these rules automatically when you select a key.

Where do the keys and BPM values come from?

Each track carries a Camelot key, a BPM value and a genre in the database. Key and tempo come from automatic analysis, which agrees with a trained listener on roughly 80–90 % of typical electronic tracks — always check a surprising match by ear.

Does Track Finder cost anything or need an install?

The harmonic search is free and runs in any modern browser; no download is required. Track Finder can also be added to the home screen as a web app. A free account adds playlists and play history.

What else can Track Finder do?

Besides the key-compatible track search, Track Finder publishes a harmonic mixing knowledge base (Learn), hosts harmonic DJ mixes, and offers a loop slicer that cuts a track into beat-accurate eight-bar loops with separated stems for live, in-key mashups.

What is Track Finder?

Track Finder is a harmonic mixing database and DJ key finder. It answers one question: which tracks will mix cleanly with the one I am playing? Select a key on the Camelot wheel and Track Finder lists every song in a compatible key — filterable by BPM range and genre — from a catalogue of over 577,000 tracks across 41 genres. It runs free in the browser and is operated from Düsseldorf, Germany.

It is not a song-recognition app: Track Finder does not identify a song from a recording. It finds the next track, not the current one.

How harmonic mixing works, in four rules

Same code (8A → 8A): the safest blend — both tracks share every note of the scale.
One step (8A → 7A or 9A): a smooth key change; the scales differ by a single note.
Relative key (8A → 8B): minor to major with the same notes — a mood change, not a clash.
Energy boost (8A → 10A): two steps up lifts the set; use it on a breakdown or a drum-only section.

The full theory — all 24 keys, Open Key notation, how key detection works and when to break the rules — is in the guide Harmonic Mixing Explained.
