Compatible moves
While a track in 10B is playing, moving to these keys sounds harmonic. The more notes two keys share, the smoother the blend.
| Move | Key | Shared notes | When to use it |
|---|---|---|---|
| Same key | 10B D major | 7/7 | The safest move. Two tracks can play over each other for a long time. |
| Relative key | 10A B minor | 7/7 | The same seven notes; moves from major to minor and darkens the mood. |
| One step up (+1) | 11B A major | 6/7 | A fifth up. Raises the energy a notch; only one note differs. |
| One step down (−1) | 9B G major | 6/7 | A fifth down. Lowers the energy slightly and relaxes; only one note differs. |
| Diagonal move | 9A E minor | 6/7 | −1 and switch letter: from major to the previous minor. Only one note differs. |
| Two steps up (+2) | 12B E major | 5/7 | A whole tone up; a clear energy lift. Needs a short, clean transition. |
| Semitone up (+7) | 5B E♭ major | 2/7 | The well-known “energy boost”. Few shared notes, so use it for a quick transition without vocals. |
| Parallel key | 7A D minor | 4/7 | Same root note, other mode. The mood changes noticeably; use with care. |
When you change the pitch
With key lock off, changing the pitch also shifts 10B. About 6% equals one semitone; values in between land between two keys and sound out of tune.
| Pitch | Semitones | Resulting key |
|---|---|---|
| -8% | -1.44 | ≈ 3B D♭ major between keys |
| -6% | -1.07 | 3B D♭ major |
| -4% | -0.71 | ≈ 3B D♭ major between keys |
| -2% | -0.35 | ≈ 10B D major between keys |
| +2% | +0.34 | ≈ 10B D major between keys |
| +4% | +0.68 | ≈ 5B E♭ major between keys |
| +6% | +1.01 | 5B E♭ major |
| +8% | +1.33 | ≈ 5B E♭ major between keys |
