Terms | Definitions |
|---|---|
 oblique motion | one voice remains stationary while the other voice moves; soprano stays on the same tone while bass moves or soprano moves while bass maintains the same tone |
| contrary motion | the two voices move in opposite directions |
| similar motion | the two voices move in the same direction |
| half cadence | ends on V (dominant) of a chord; use common tone, move other voices to nearest chord tone - contrary or oblique motion if possible, move three upper voices contrary to bass voice |
| chord tone | 1,3,5, and sometimes 7 |
| plagal cadence | IV to I (subdominant to tonic) use common tone and move other voices to nearest chord tone |
| progression of I to IV (tonic to subdominant) | not a cadence, be careful of the motion vs. the common tone, move upper voices contrary to the bass, don't double F# in 7 diminished 6! In successive inversions you may use unusual doublings |
| deceptive cadence | V to vi try to use contrary or oblique motion to the bass and give yourself some room to work with the soprano line, This refers to any time that the music seems to lead up to a cadence, but then doesn't actually land on the expected tonic, and also often does not bring the expected pause in the music |
| perfect authentic cadence | V to I or V7 to I (always ends on the tonic) root in bass (root position) in both chords (and the soprano and bass in the tonic) |
| imperfect authentic cadence | does not have the 3 root rule, May refer to an authentic (V-I) cadence in which the chord is not in root position, or the melody does not end on the tonic. OR may mean a cadence that ends on the dominant chord |
| root position | In root position, the root, which is the note that names the chord, is the lowest note. The third of the chord is written a third higher than the root, and the fifth of the chord is written a fifth higher than the root (which is also a third higher than the third of the chord). So the simplest way to write a triad is as a stack of thirds, in root position. |
| perfect plagal | also uses the 3 root rule |
| imperfect plagal | does not use 3 root rule NOTE: contrary motion |
| open position | more than an octave between tenor and soprano |
| close position | less than or equal to an octave between tenor and soprano |
| chord spacing rule | put the widest space between the lowest voices |
| common chord rule | avoid doubling the leading tone |
| first inversion | 3rd is in bass double the bass EX: chord is CEG becomes CEEG |
| second inversion | 5th is in bass double the bass EX: chord is CEG becomes CEGG |
