A semitone rise between tracks creates an energy boost by adding 7 (one semitone) or 2 (two semitones) to the Camelot number

Raising the key by one or two semitones between tracks is a classic pop and DJ technique for adding energy — it mimics the final-verse key change used in pop songs for decades. In the Camelot system, the formula for finding the new track’s position is: for a one-semitone rise, add 7 to the current Camelot number (mod 12); for a two-semitone rise, add 2. A two-semitone jump is generally more reliable than one semitone for mix compatibility. Because the new key is not harmonically related to the previous one, this technique works best in short transitions (not long blends) to avoid clashing harmonics during the overlap.

Examples

Currently playing at Camelot 5A: add 7 to get 12A (one semitone up), or add 2 to get 7A (two semitones up). The new track sounds ‘lifted’ compared to the outgoing one.

Assessment

A DJ is at Camelot 8B and wants a two-semitone energy boost. Calculate the target Camelot position. Then explain why this technique should be used in short transitions rather than long blends.
