Harmonic Analysis - Chromatic

Harmonic Analysis is the understanding of the functional sequence of chords. It is the process used to analyze the harmonic structure of a progression, song, or composition. This analysis is then used to make scale selections for improvisation and chord substitution. This lesson covers the Chromatic harmonic principle.

Harmonic Analysis - Chromatic

Harmonic Analysis is the understanding of the functional sequence of chords. It is the process used to analyze the harmonic structure of a progression, song, or composition. This analysis is then used to make scale selections for improvisation and chord substitution. This lesson covers the Chromatic harmonic principle.

Chords ascending or descending by Chromatic half steps between roots. The root and species are NOT in the harmonized chord chart.

WORKSHEET NOTATION: Label these chords with a flat or sharp, UPPERCASE roman numeral, and chord type using the Roman numeral of its unaltered scale degree. The tonality or key center does not change.

Using the above chord progression and the Major Harmonized Chord Chart we see a II V I in the key of C major. But – what about that Eb7. The root Eb is not in the key of C major. An Eb7 chord is V , the dominant chord in the key of Ab Major or Ab Minor . The progression has not modulated the a new tonal center. This chord is functioning as a Chromatic connection from Cmaj7 to Dm7. Label this chord as a bIII7 chord.

Example 2

Using the previous chord progression and the , the Roman numerals I bIII7 II bII7 would be applied.

Example 3

Using the previous chord progression and the , the Roman numerals III bIII7 II bII7 would be applied.

Chromatic chords are sometimes a result of using the Minor Third Substitution Principle to be covered in a later chapter.

Try these Chromatic Major chord progressions in various major keys.

NOTE: See the Secondary Dominant section of the Partial Diatonic chapter for information on Diminished chords.And, why they are not always Diminished chords.

Common Chromatic Chords

Common chromatic chords with their Enharmonic Equivalents .

♭II or ♯I
♭III or ♯I
♭V or ♯IV
♭VI or ♯V

{{-- bII or #I bIII or #II bV or #IV bVI or #V bVII or #VI %>

Song Examples

Most folk, rock and blues songs remain in one key. Most Jazz and Pop standards will modulate to new key centers.
