11-3 CHORD PROGRESSION
8. Tonic Chord.
The principal note and chord of a key is the tonic. Practically all music gives preference to one note or chord, the tonic, making it the tonal center to which all other tones and chords are related. Any triad can follow the tonic triad. Any triad can progress to the tonic triad without affecting the type of chord progression.
9. Types of Chord Progressions.
There are four types of chord progression: normal, repetition, retrogression, and elision.
10. Normal Progression.
Normal progression occurs when chords progress from left to right through each successive chord group. Normal progression is shown on the chord group chart in Figure 11-21.

a. Repetition occurs when a chord is consecutively repeated. The repeated chords can be spelled differently or can be in different positions. In Figure 11-22, the tonic chord is repeated.

b. Repetition also occurs when a chord is followed by another chord within the same chord group. In Figure 11-23, the IV chord is followed by the ii chord. Both chords are group two chords and have subdominant function.

Retrogression occurs when chords progress from right to left on the chart away from the tonic chord (Figure 11-24). This movement can occur through each successive chord group or can skip a chord group. Normal progression usually follows retrogression.

a. The most common retrogressions are:
b. Less common retrogressions are:
a. Elision occurs when one chord group is skipped in an otherwise normal (left to right) movement on the chord chart. In the first measure of Figure 11-25, the group two chord has been skipped. In the second measure of Figure 11-25, the group three chord has been skipped. Normal progression usually follows an elision.
