Scales and Chords

Tell the difference between notes in a line and notes stacked together.

One idea

Plain-language explanation

A scale is notes walking one after another, like steps up a staircase. A chord is notes sounding together, like friends standing side by side for a photograph. Both use the same musical alphabet.

Do this now

Three tiny steps

  1. Play or sing C, then D, then E: that is a tiny scale.
  2. Play C and E together if you have a keyboard: that begins a chord sound.
  3. Listen for the difference: one-after-another versus together.

Two-minute practice

Try it yourself

Say: “Scale means a line. Chord means together.” Then demonstrate each one with any two or three notes.
