Notes on the neck · Exercise 03

Octave shapes

Goal
Use two octave shapes to find any note on every string.
Time
15 min

You'll

  • Learn the two-strings-over, two-frets-up shape
  • Add one fret when crossing the B string
  • Map every G, then every C, up to fret 12

Octave shapes

The basic shape

  • Same note, one octave up: two strings over, two frets up
  • Works low E → D string, and A → G string
  • Example: G at fret 3 (low E) → G at fret 5 (D string)
  • Fingers 1 and 3, or 1 and 4

Crossing the B string

  • Landing on or crossing the B string: two strings over, three frets up
  • Works D → B string, and G → high E string
  • Example: G at fret 5 (D string) → G at fret 8 (B string)
  • Remember: +2 frets normally, +3 when the B string is involved

Every G up to fret 12

  • Low E 3 → D 5 → B 8
  • A 10 → G 12 (open G is its 12-fret twin)
  • Both E strings match fret for fret

Hear it

Do this

  1. Play every G in the diagram, lowest to highest. Count them.
  2. Map C yourself, starting at A string fret 3. You should hit fret 8 (low E) and fret 5 (G string).
  3. Daily: one note, all six strings. Log it.

Check

  • You can find any G or C on all six strings without the diagram
