sense of tension

Cadence
________- The harmonic, melodic, and rhythmic conclusion to a phrase.
slow harmonic rhythm
A(n) ________ creates a sense of calm and stability.
harmonic progression
The ________ determines the chords played in a piece of music.
lowest voices
Outer voices- The highest and ________ in a musical texture.
harmonic structure
The ________ is an important aspect of a piece's overall sound and emotional impact.
fast harmonic rhythm
A(n) ________ creates a sense of tension and excitement.
harmonic rhythm
The ________ determines how quickly those chords change.
Voice leading
The art of arranging musical voices in a way that creates smooth and logical progressions
Motion
The direction in which the melody moves in relation to the bass line
Contrary motion
Moves the melody in the opposite direction of the bass
Oblique motion
When one voice remains on the same note and the other moves in either direction
Similar motion
When the bass and the soprano move in the same direction but at different intervals
Parallel motion
Where the soprano and bass move in the same direction and at the same interval
Outer voices
The highest and lowest voices in a musical texture
Open and closed positions
The spacing between the voices in a chord
Cadence
The harmonic, melodic, and rhythmic conclusion to a phrase
Cadences end with only three chords
I (i), vi (VI), or V (v)
Authentic cadence
The most common phrase-ending chord progression that uses the dominant chord to set up the tension and the tonic for the release
Perfect Authentic (PAC)
Concluding cadence that requires both dominant and tonic chords to be in root position
Imperfect Authentic (IAC)
Weaker authentic cadence that has either chord inverted, or has a chord member other than the root in the soprano of the tonic chord
Plagal Cadence (PC)
Weaker progression using the subdominant to tonic to provide the resting point
Deceptive cadence (DC)
Ending progression where the dominant chord is unexpectedly resolved to the submediant instead of the tonic
Half Cadence (HC)
Unresolved tension used especially in the middle of a melody
Phrygian Half Cadence (PHC)
Occurs in a harmonic minor
Chordal seventh
A seventh note added to a chord, creating a four-note chord
Voice leading
The art of moving from one chord to another in a smooth and melodic way
the chordal seventh can be added to
any chord, including major, minor, diminished, and augmented chords.
the chordal seventh should resolve in a
melodic way by moving down a half step to the third of the next chord.
seventh chords can be used to
create tension and release, adding interest and complexity to the harmony.
Harmonic progression
A series of chords played in a specific order
Common progressions
I-IV-V
ii-V-I
Progressions can be
simple or complex
A fast harmonic rhythm creates
tension and excitement
A slow harmonic rhythm creates
calm and stability
