Ch. 1-12 Flashcards
What is four-voice texture?
four separate moving voices forming chords
What is a chorale?
used in German protestant churches during the time of Bach
What is stylistic practice?
rules for writing four voice texture
What is a common tone?
a note that is in two successive chords
What is doubling?
In a chord, a note that is sounding in two voices
What is the stylistic practice when both chords are in root position and the two chords lie a perfect 4th or 5th apart?
keep the common tone and move all other voices to closest tone in the chord, otherwise use good voice writing by moving each voice to the closest tone
What is overlap in four part writing?
when a voice goes higher than the note previously sang by an adjacent voice
What are crossed voices?
when the voices are not in SATB order
What is proper spacing in four part writing?
no more than an octave between soprano, alto and tenor. between tenor and bass doesn’t matter
What are unequal fifths?
one voice moves a P5 and the other moves a d5
What is close position?
when soprano, alto and tenor are within an octave
What is a circle progression?
chords moving in ascending fourths or descending fifths
What are perfect intervals?
P1, P4, P5, P8
What are diminished intervals?
a perfect interval lowered a half step or a major interval lowered a whole step
What is a macro analysis?
naming the chord with the letter corresponding to the roman numeral
What are diminished triads?
m3 + d5
What is the stylistic practice when both chords are in root position and the two roots lie a 3rd apart?
Keep both common tones and move the remaining upper voice stepwise
What is the stylistic practice when the roots lie a 2nd apart?
Move the upper 3 voices in contrary motion to the bass making sure that each moves to the nearest chord tone
What is the stylistic practice when chords are repeated?
Maintain proper doubling and range of voices, and keep the usual order of voices
What is the stylistic practice for voice leading in first-inversion major and minor triads (not dim)?
Double any triad factor that facilitates smooth voice leading. Never double the leading tone.
What is the stylistic practice for the leading tone triad (vii*)?
most often progresses to the tonic. doubling the bass is preferred, but also 5th factor
What is the stylistic practice for the ii*6 triad in minor keys?
most often progresses to the dominant. double the bass note, or the root
What is tonality?
an organized system of tones in which one tone (the tonic) becomes the central point to which the remaining tones are related
What are the four ways you may use a 6/4 chord?
cadential
passing bass
arpeggiated bass
pedal bass
What part writing rules can NEVER be broken?
no parallel P5s, P1s, or P8s
use a voice’s proper range
do not write melodic A2s or A4s
never double the leading tone of a scale
What is a tritone?
A4 or D5, which divides the octave into 2 equal parts
What is a phrase?
a substantial musical thought, which ends with a cadence
What is a harmonic cadence?
closes a phrase or section of music
What is an imperfect cadence? List the 3 qualifications for an imperfect cadence.
V to I. Does not meet requirement for PAC. Tonic is highest sounding note in tonic or both are in root position.
What is a half cadence and a plagal cadence?
HC - anything to V
plagal - IV to I
What is a phrygian half cadence?
iv6 to V
What is a deceptive cadence?
V to anything but I
What is an escape tone?
approached by step and left by skip in opposite direction
What is an anticipation?
note in the next chord that is played before the chord
What is a suspension? Include how many parts and the name of each part.
note from previous chord held into the next.
3 parts = preparation, suspension and resolution
What is an appoggiatura?
approached by skip and left by step in opposite direction
What are changing tones?
two successive nonharmonic tones
What is a motive?
a melodic or rhythmic pattern occurring throughout a piece
What is the difference between a real sequence and a tonal sequence?
a real sequence contains continuing segments that are exact transpositions or the first segment. a tonal sequence accommodates the diatonic scale
What is a modified sequence?
some of the segments may be decorated or embellished in a way that does not destroy the original character
What is a false sequence?
repeats part of a figure and states the remainder in sequence
