The Ruler

Choose a note collection

A scale limits your ingredients; it does not write the melody for you.

Take the guided lesson

Two routes through the same octave

The first climbs every fret. The second leaves some pitches out. Both use the same steady spacing between attacks; listen to the different distances between pitches.

The collection and the phrase are different things

A scale names an ordered collection of pitches, often shown from one tonic to its octave. A melody chooses from a collection, repeats notes, jumps, rests, and gives them rhythm.

Section 2 taught you to place attacks and silences. Keep that skill: a scale played as an unbroken staircase is only one possible use of its notes.

Pick every one that applies

Which phrases use only notes from C major?

Find the collection on a real string

Find C D E F G A B on the B string, using frets 1, 3, 5, 6, 8, 10, and 12. The same seven pitch classes appear elsewhere on the neck.

Use C at B-string fret 1 as your anchor; find D at 3 and E at 5, then continue by sound and spacing.

What to keep

Takeaways

  • A note collection is material for music, not a compulsory finger exercise.
  • Use the rhythm you already learned to turn a collection into a phrase.
