    4B into 11B (A major) is seven Camelot numbers, one semitone between the tonics. That is a key clash, not a boost. When a note says "+7" and means seven semitones, it is the one-step-up move above.

The energy boost

4B into 6B (B♭ major) is two steps up the wheel, a whole tone. DJs call that an energy boost. Sonata flags it as a key clash, not as In key. Hear it before you rely on it.

Seven semitones is not this move. That is one step up the wheel, already In key. Seven Camelot numbers is one semitone, and that clashes too. Harmonic mixing energy boosts walks through both. Check the pair in the key checker.

Mixing from here

  • The smooth moves are 3B (C♯ major), 5B (E♭ major) and 4A (F minor). Sonata calls those In key.
  • 6B is two steps up, the energy boost. Sonata calls that a key clash. Hear it before you rely on it.
  • Leave the pitch alone. Sonata does not transpose, so a clash stays a clash.
  • A smooth key is not a smooth blend on its own. If the tempos are more than about 10 percent apart, or the beat is unclear, the pair does not get a beat-locked blend. It gets an echo out or a plain fade.
  • Play the pair. The label is a flag, not a listen.
