Every melody note has a relationship to the underlying chord. Understanding this relationship is the key to writing melodies that sound intentional and expressive. Notes fall into three categories:
Chord Tone
Root, 3rd, 5th, or 7th of the chord. These notes define the harmony and sound stable. You can hold them as long as you want.
Scale / Passing Tone
Notes in the key but not in the chord. They add motion and color. Best used on weak beats or as connectors between chord tones.
Chromatic Tone
Notes outside the key. Maximum tension. Use as brief approach notes or for dramatic effect, then resolve to a chord tone.

Music is a conversation between tension and resolution. When a melody note is a chord tone, the listener feels stability. When it is a passing tone, there is gentle forward motion. When it is a chromatic tone, maximum tension creates a strong pull toward resolution.
Resolution Target
Chord tones are where melodies "land." Strong beats should favor chord tones for stability.
Passing Motion
Scale tones connect chord tones by step. They work best on weak beats and short durations.
Approach Notes
Chromatic notes approach a chord tone from a half step away, creating expressive tension.
| Strategy | Description | When to Use |
|---|---|---|
| Target chord tones on strong beats | Land on Root, 3rd, 5th, or 7th on beats 1 and 3 | Always works. The safest approach. |
| Use passing tones on weak beats | Stepwise scale tones between chord tones on beats 2 and 4 | Creates smooth melodic motion |
| Neighbor tones | Step up or down from a chord tone and return | Adds ornamentation and interest |
| Chromatic approach | Approach a chord tone from a half step below or above | Jazz and blues feel. Very brief. |
| Anticipation | Play the next chord's tone slightly early | Creates forward momentum at chord changes |
1-3-5 Arpeggio
Outlining the chord directly. Strong and clear. The foundation of bugle calls and fanfares.
Stepwise Motion
Moving by scale steps. Smooth and singable. Most melodies are predominantly stepwise.
Leap then Step Back
A large interval followed by stepwise motion in the opposite direction. Creates drama then resolution.
Enclosure
Approach a chord tone from both above and below (e.g., D-B-C over Cmaj). Common in jazz.
