See Theory Guide for more detailed information on how to use the Harmonizer.
Major and Natural Minor Scales

This section shows the notes, modes, and chords of the Major scale and Natural Minor Scale.

It also shows the interval distance between the notes that make up the chords in every key.

The process for arranging the notes to create the chords of a scale is called harmonization. This process is the secret to understanding how notes, chords, and scales relate to each other.

Dial the Harmonizer to the desired key to see all its harmonic relationships.

Common Chord Substitutions

You can create harmonic variety by the chord choices you make. This section shows you what chords make good substitutions for other chords.

It also shows the scale degree and chord function of each chord.

Use it to add more interesting harmonies to your arrangements and compositions.

Chord Progression Map

This section shows root tones that make up many popular chord progressions. After dialing to the desired tonic note, chord progressions are created by following the paths indicated by the arrowed lines.

Roman numerals are used to indicate the scale degree each note belongs to. Two numerals are represented to accommodate for Major and Minor keys.
Melodic Minor Scale

This section shows the Melodic Minor scale, a scale popular in Jazz. This section shows the modes and the chords that make up the scale.

Harmonic Minor Scale

This section shows the Harmonic Minor scale, a scale popular in Latin and other ethnic music. This section shows the modes and the chords that make up the scale.

Pivot Chord Modulation

This section shows chords that can be used to modulate from one key to another. When a chord belongs to two different keys, that chord can be used to "pivot" the tonal center of a song to a different key.


This section is used to help you transpose a song from one key to another.

Find the key you want to go "from" in one of the windows on the lower row. Then, turn the dial until the key you want to go "to" appears above your "from" key.

At this point the Harmonizer shows the notes of the original key and what they need to be changed to in the new key.
