ABSTRACT
A harmonic sequence is a repeating pattern of root motion in a succession of chords. In sequences, tonal function is often suspended temporarily as the recurring root and bass motion assumes priority. Harmonic sequences that do not conform to tonal syntax typically prolong a function or connect one function to another. Diatonic seventh chords that are otherwise uncommon in Classical music often appear in sequences. Any or all of the root-position triads in a fifths sequence may be replaced with inverted chords, seventh chords, or both. Diatonic seventh chords that are otherwise uncommon in Classical music often appear in sequences. The descending thirds sequence most often includes “connector chords” inserted between the regular chords of the pattern. The chords forming the descending thirds sequence are underlined. This sequence is found most often in a three-voice texture, which eliminates the disjunct voice.
