Section 1 (Theory/Harm) - Extended and Altered Chords Flashcards
extended chords or chromatically altered chords add what to a piece of music
color
what are altered chords used as
a secondary dominant function that suggests a momentary chord change without modulating to a different tonic
what is the most commonly omitted note in an extended chord
the 5th
what is often omitted in an 11th chord
the 3rd
what is often omitted in a 13th chord
5th 9th and 11th
where are 9th chords commonly found
on dominant and supertonic chords
how does the 9th resolve
it moves downward a step to the nearest diatonic note of its resolution note
how can a 9th resolve up
only if there is a passing tone to fill the gap of the third
what chord is most often chromatically altered
the dominant
what chords do augmented chords happen on in major
1 4 and 5
is the raised 5th ever doubled
no too dissonant
how does the raised fifth resolve
up a half step to the target chord
the lowered 5th can appear on what chord
dominant
what position can a dominant b5 chord be in
root or first
how does the b5 resolve
to the root of the tonic chord
what is a raised root chord
take the root of the chord about to be tonicized. go down a half step and fill in the chord.
can be vii triad vii7halfdim or viii7diminished
what is another approach to altered chords
the use of chord scales especially when in mixolydian
in mixolydian what triads have a different tone color than in their parallel major
I7, 2, 5, and 7
the use of the mixolydian chord is determined by
the target chord
if the target chord contains a major 3rd
the secondary dominant seventh chord generally takes mixolydian as a chord scale
if the target chord contains a minor 3rd
the secondary dominant seventh chord generally takes mixolydian b13 as a chord scale
what chords does the lydian mode alter
the II becomes major
#4 becomes diminished
7th becomes minor
what do all subV7’s that resolve down by a half step take as their chord scale
lydian b7
what are chord scales
scales built on the different scale degrees of a key signature producing each mode
