MUS 2302 Theory IV - Test #2

Question 1

Extended Tertian Chords

Answer 1

Counted to the farthest extension (must include every NATURAL extension between)

All extensions add M9, P11, M13 (5th can be omitted)

Question 2

Altered Tertian Chords

Answer 2

Counted to the farthest NATURAL extension (must include everything between), then alterations listed from highest to lowest

All extensions add M9, P11, M13 (5th can be omitted)

Question 3

Split-Note Chords

Answer 3

C(3!) = split 3rds; split root C(1!) will always use a root 1/2 step up, 5ths can be split flat or sharp C(5!)

Question 4

Polychords

Answer 4

Must be separated by either register or voice; written as top chord over bottom chord (inversions not necessary)

Question 5

Quartal/Quintal Harmony

Answer 5

4ths/5ths (don’t have to be P4s/P5s only)

Quartal/quintal = __number of notes__ x __interval__ on __root__ (e.g. 4x4 on A is a four note quartal chord building up from A)

Question 6

Secundal Harmony

Answer 6

Also includes 7ths

Question 7

Tone Clusters

Question 8

Whole-Tone Chords

Answer 8

Four or five or more notes from the whole tone scale

Question 9

Open Fifths

Answer 9

Only two pitch classes; only P5

Question 10

Mixed-Interval Chords

Question 11

Pitch vs. Pitch Class

Answer 11

C4, C5 = pitch, all C’s included in the pitch class of C

Question 12

Set vs. Set Class

Answer 12

Set = any set of numbers; set class = sets that share the same cardinality and interval relations??

Question 13

Interval vs. Interval Class

Answer 13

Interval = an interval between two specific pitches; interval class = the type of interval in half steps (1, 2, 3, 4, 5, 6) reduced to the tritone

Question 14

Transpositional Equivalence

Question 15

Inversional Equivalence

Question 16

Normal Order

Answer 16

Any set rearranged to be ascending or descending

Question 17

Best Normal Order

Answer 17

Any ascending set rearranged to be the most compact possible

Question 18

Prime Form

Answer 18

A set in Best Normal Order, reset to begin on zero

Question 19

Forte Labels

Question 20

Cardinality

Answer 20

Number of pitch classes in a set

Question 21

Dyad

Answer 21

Two note chords

Question 22

Trichord

Answer 22

Three note chords

Question 23

Tetrachord

Answer 23

Four note chords

Question 24

Pentachord

Answer 24

Five note chords

Question 25

Hexachord

Answer 25

Six note chords

Question 26

Septachord

Answer 26

Seven note chords

Question 27

Octachord

Answer 27

Eight note chords

Question 28

Nonachord

Answer 28

Nine note chords

Question 29

Complementary Sets

Answer 29

All the pitch classes NOT contained in a set

Question 30

Interval-Class Vector

Answer 30

The inventory of interval classes contained in a set

Question 31

Z-related sets

Answer 31

Share an interval class vector with another set of the same cardinality

Question 32

Transpositional Operations (Tn)

Answer 32

Adding n to each pitch in a set, reset to Mod12

Question 33

Inversional Operations (TnI)

Answer 33

Subtracting each pitch in a set from 12, then performing Tn

Question 34

Degrees of Symmetry

Answer 34

When a set can be inverted/transposed and the result maps onto itself; every set has at least one: T0

Question 35

Transpositional Symmetry

Answer 35

When performing Tn results in the same set

Question 36

Inversional Symmetry

Answer 36

When performing TnI results in the same set

Question 37

Multiplicative Operations (Mn)

Answer 37

Multiplying each pitch in a set by n, reset to Mod12

Question 38

Subsets

Answer 38

Any set contained within a larger set (e.g. 237 from 1235678)

Question 39

Supersets

Answer 39

Any set which contains a smaller set as well as something more (e.g. 1246 is a superset of 146)

Question 40

All trichord prime forms
