Harmonic Mixing

Rule #1: The Basics

Same key: Always works. Safe choice.

±1 position: Perfect blend. This is your main move.

±2 positions: Slight tension, use EQ to smooth.

Opposite (±6): Creates push. Advanced, use sparingly.

How to Find Keys

• Rekordbox: Auto-analyzes all tracks. Plot by key.
• Serato: Built-in key detection. Same thing.
• Mixed In Key: Standalone software, £20. Most accurate.
• Your ear: Listen for root note. Takes practice.

Beatmatching (The Other Half)

• Match BPM (or use sync to learn)
• Align beat grids on screen
• Phrase match: start on beat 1
• Listen in headphones while blending

Quick Transitions

• Clean blend: EQ bass, beatmatch, crossfade.
• Echo out: Reverb tail → silence → next.
• Filter sweep: Low-pass on crossfader.
• Cut: Kill track 1 on beat 1 of track 2.
