Perfect Cadence
V or vii(diminished) going to a I chord.
Half (Imperfect) cadence
Anything to a WV
Authentic Cadence
Classified as either perfect or imperfect.
Three things have to happen to be considered an authentic cadence:
- must be a V-I progression not a vii(diminished)
- Both chords must be in root position
- The highest note of the I chord must be the tonic of the scale.
If it does not meet these three requirements it is considered an imperfect cadence.
Plagal cadence
IV-I
Deceptive cadence
Phrase ends with a V chord going to something other than a I.
What is a nonharmonic tone
Notes that do not belong in a chord.
Passing tone
approached by step and continues in the same directions by step.
Accented passing tone
a note that does not belong to any chord and occurs with the second chord.
Neighboring tone
approached by step and then returns by step to the original note. If it occurs with the second chord it is called an accented neighboring tone.
Anticipation
Approached by step and remains the same. Basically a note of the second chord played early.
Escape Tone
Approached by step and skips in the opposite direction.
Appoggiatura
Approached by skip and then steps in the opposite direction.
Accented and occur with the second chord.
Suspension
Keeps a note the same and then steps down
Accented
Retardation
Keeps a note the same and then steps downward
Accented
Changing Tones
Two nonharmonic tones in succession. The first is approached by step and then skips in the opposite directions to the second harmonic tone which then resolves by step. Sometimes called double neighboring tones or a neighboring group.
Invert
move the lowest note in a group an octave higher.
Perfect intervals will always invert to another perfect interval.
A perfect fourth will invert to a perfect fifth and a perfect fifth will invert to a perfect fourth.
Minor intervals and major intervals invert to each other.
Thirds and sixths invert to each other.
Seconds and sevenths invert to each other
Diminished and augmented invert to each other.
(knowing these will help with quick inversions)
Triad inversions
Move the lowest note of the triad up an octave.
The lowest note determines the name of inversions. It is called the bass note. When the lowest note is the root of the chord, the chord is in root position.
When the bass note is the third of the chord it is considered to be in first inversion.
When the fifth is the lowest note of the chord it is in second inversion.
In seventh chords, when he seventh is the lowest note of the chord it is considered to be in third inversion.
Parallel Motion
Both voices move in the same direction by the same interval.
In order to achieve a level of independence of line for all four parts, parallel motion of Perfect Octaves, Perfect Fifths, and Unisons should be avoided. Since these are the lowest intervals on the overtone series, when two or more voices move in parallel motion in these intervals, they can blur together and sound like only one voice (in the case of unisons, they actually become one voice). Parallel motion by thirds, fourths and sixths is acceptable and often desirable, however, two voices should not move in parallel motion for several beats in succession
Similar Motion
when both voices move in the same direction, but by different intervals
