Harmonic progression


Harmonic progression
Harmonic Progression

  • Defined as the movement from one chord to the next; a succession of chords or chord progression

  • A principal organizing force


Root relationships
Root Relationships

  • The relationship of chords to the prevailing tonality

  • The intervals formed by the roots of adjacent chords


Chord progressions
Chord Progressions

  • Circle progression

  • Non-circle progression

  • Ascending fifths

  • Ascending seconds

  • Descending thirds


Circle progression
Circle Progression

  • The most common and strongest

  • Adjacent chord roots in ascending fourth or descending fifth (same note when inverted)

  • The basis of all harmonic progression

  • Found in succession: ii-V-I, or even

    vi-ii-V-I


Circle progression1
Circle Progression

  • Can derive many harmonic patterns from this progression: I-IV-vii°-iii-vi-ii-V-I, and many can be used based on this progression. Note that the progression starts and ends on the tonic (see figure 10.2) in book.

  • Circle progression is a drive toward the tonic


Non circle progression
Non-Circle Progression

  • Anything that isn’t circle

  • Used in conjunction with circle progression

  • Adds variety to the music


Ascending fifths
Ascending Fifths

  • I-V, IV-I, V-ii, vi-iii, iii-viiº, and ii-vi

  • Can be descending fourth also

  • Provides relief from the constant motion of circle progression

  • Most common is I-V

  • Half cadence is a good example of this progression


Ascending seconds
Ascending Seconds

  • Adjacent chords whose roots are a second apart: IV-V, V-vi, I-ii, ii-iii, iii-IV, and viiº-I

  • Used to prepare a shift from the circle progression to another

  • The vii° chord is often used in a dominant function as a vii°6 to a I


Descending thirds
Descending Thirds

  • I-vi, vi-IV, IV-ii, iii-I, and V-iii

  • Chords whose roots are a third apart

  • Provide contrast and facilitate change from circle progression to another

  • Used in harmonic movement away from the tonic or in a longer chord series


Tonic 6 4 triad
Tonic 6/4 Triad

  • Used in a cadential manner as in I6/4-V-I

  • A decoration of the V chord that follows it


Repeated chords
Repeated Chords

  • No progression takes place with repeated chords, whether inverted or not


Harmonic rhythm
Harmonic Rhythm

  • The frequency of harmonic changes in a composition

  • Typically defines the meter

  • Can be slow or fast in its changes


Harmonizing a chorale phrase
Harmonizing a Chorale Phrase

  • You must use half or authentic cadences for the final two notes of each phrase

  • You should use circle progressions throughout each phrase

  • Harmonize each melody note with one chord. It is possible to repeat chords, but add inversions for variety

  • Use first inversion chords to make a smoother bass line

  • Shape the bass line carefully to make it a singable melodic line.

  • Avoid overuse of ascending third and descending second progressions
