A guitar harmony generator creates a second pitched part from your melody. Guitar Harmony Helper works from notes you enter in tablature. Start with a short lick and use playback to compare ideas as you arrange.

Try this four-note guitar riff

In standard tuning, the top tab line is the high E string. Choose quarter notes and enter frets 5, 7, 9, 10 on that string, moving right between notes. These notes are A, B, C♯, and D.

Make your first harmony

  1. Open the free browser demo. Wait for loading, start your riff, and enable sound.
  2. Enter the four quarter notes. They fill the demo’s one 4/4 bar.
  3. Choose a scale. Use Detect Scale and select D major for this example.
  4. Add a harmony. Choose + Add Harmony, check the scale, and select an interval such as 3rd Above.
  5. Listen separately and together. Compare Main Guitar, Harmony, and Play All Together.
  6. Explore Locations. Try another fretboard region or string and check the result on your guitar.

Why does the scale matter?

A harmony depends on the musical context. Changing the selected scale or interval can change the second part. Use the generator to explore options, then choose the sound that suits your song. See how to find scales that fit a riff.

Can it listen to a recording?

This walkthrough starts with fret numbers entered in the tab editor. It does not describe audio transcription or a live guitar effect.
