What is Open Key notation?

Open Key is an alternative DJ key notation system that uses numbers 1–12 followed by 'd' for major (dur) or 'm' for minor (moll). It maps the same harmonic relationships as Camelot but with different codes.

Why are there multiple key notation systems?

Different DJ software and analysis tools adopted different conventions. Knowing standard key names, Camelot, and Open Key lets you work with any platform or collaborate with producers using a different system.

How do I convert a Camelot code to a standard key?

Look up the number and letter in the converter. For example, 8A is A minor and 8B is C major — the relative major and minor share the same Camelot number.
