What Are Chord Tones?

Chord tones are the notes that make up a chord.

For example, the chord tones of a C major chord are C, E, and G. When C major is playing, playing any of these three notes in your melody produces a stable, consonant sound that locks in with the harmony underneath.

Why Chord Tones Are “Safe” for Melody

When a melody note and the chord underneath it are playing at the same time, your ear hears chord tones as stable and at rest. Notes that aren’t part of the chord create tension — they want to move somewhere.

When you’re starting out, writing melodies using only chord tones is the most reliable way to sound musical right away.

Chord Tones vs. Scale Tones

Chord tones are closely related to another concept: scale tones.

TypeWhat it meansHow safe?
Chord tonesNotes in the chord (e.g., C major = C · E · G)★★★ Most stable
Scale tonesOther notes in the key’s scale (e.g., C major scale = C D E F G A B)★★☆ Natural for melody
Outside notesNotes outside the scale★☆☆ Use with care

Try It in the Melody Note Guide

Open the Melody Note Guide and select any chord. The piano will highlight:

  • Green keys = chord tones (the notes in the selected chord)
  • Blue keys = scale tones (other notes in the key)

For example, with C major key and the C chord (I) selected:

  • Green (chord tones): C · E · G
  • Blue (scale tones): D · F · A · B

Try playing only the green notes over the chord. Notice how they blend in perfectly.

Applying This to a Chord Progression

Once you understand chord tones, practice applying them across a full progression. Here’s a common one:

C → Am → F → G (C major key)

ChordChord Tones
C (I)C · E · G
Am (vi)A · C · E
F (IV)F · A · C
G (V)G · B · D

As the chord changes, the chord tones change too. Landing on a chord tone when each new chord arrives makes your melody feel like it’s “following” the harmony — which is exactly what great melodies do.

Summary

  • Chord tones are the notes that make up the chord — the most stable melody choices.
  • Start by writing melodies using only chord tones, then gradually add scale tones.
  • Use the Melody Note Guide to see chord tones and scale tones highlighted on a piano for every diatonic chord.
