Understand the perfect fifth — the most consonant interval after the octave.

Instructions

  1. Set Level 2 on Guitar. Select C Major.
  2. Find the blue dots — those are Perfect 5th (P5) notes, 7 half steps above the root.
  3. Now select a Power Chord (C5). Only the root (red) and fifth (blue) remain.
  4. Power chords use just R + P5 — no third, so they sound neither major nor minor.
  5. The P5 appears in almost every chord type. It's the "glue" of harmony.
TIP

On guitar, locate the perfect fifth by counting seven frets or by using a familiar power-chord shape; account for the B-string tuning shift when crossing that string.
