48
Enharmonics in post tonal music
Convenience
49
How are intervals identified in post tonal
By number of semi tones
50
Ordered pitch intervals
Number of semitones and direction moved
Labeled with +/- in semitones on bracket
51
Unordered pitch intervals
Semitones moved. Which notes comes first is irrelevant
52
Intervalic motives and how labeled
2+ intervals
Labeled over bracket with < #1 +/-, #2 +/-, etc>
53
Pitch class
One pitch in octaves
Pitch class clockface
54
Pitch class interval
Distance between two pitch classes
Ex G-A# in different octaves, orderings, and spellings
55
Ordered pitch class intervals
Number of semitones between two notes. Put into same octave as first note (ascending from first note. Second note moves octaves)
Go around on pitch class clockface
56
How to use pitch class clockface
Move clockwise or subtract first note from second
Add 12 if negative. Minus if over 12
Same as changing octaves
57
Unordered pitch class intervals
Also called?
Shortest distance between two notes
Pitch class
58
How many different ordered pitch class intervals? What happens if we add interval inversions together?
11 (semitones)
Interval inversion cuts to 6 (semitones). Makes ordered pitch class intervals (IC)
59
Interval symmetry
Intervals bottom to top are same as top to bottom
60
Interval cycles. How many? How labeled?
Start and end in same place moving repeatedly by same interval
6 options
Labeled C1-C6 + interval class
61
Retrograde
Backwards
62
Retrograde inversion
Inverted then played backwards
63
Tone row
Must use all 12 and cannot repeat
64
Row form- how many and transpositions
4 flavors 12 transpositions each and 48 total
65
Pitch class sets
Basic building blocks of post tonal
Unordered collections of pitch classes
Trichords most common
66
Normal form
How we write notes in pitch classes
Ascending order, same octave, smallest interval between, has commas
67
Transposition
How labeled
Move each note by same ordered pitch class interval
Tn with n being semitones
68
Inversion
Invert around C
Note number of semitones above C becomes note semitones below C
First interval becomes last interval
Notes reflected across pitch class clockface
69
Compliment
Notes reflected by inversion
70
How invert
Find compliment then reverse order- that’s the normal form
71
Index of inversion
N in Tn of a TnI
Semitones transposed of something that is inverted then transposed
72
12 tone row
Must use all 12 pitches and cannot repeat
73
Series
Ordered line of notes sometimes called row
74
Prime form
Original or transposed version
75
Inversion of row
Invert around first note of form
D-E becomes D-C
76
Retrograde inversion
Invert then do it backwards
77
Prime form label
Px where x is the letter it starts on
78
Retrograde prime label
RPx with x being the note it ENDS on
79
12 tone matrix
Convenient way of presenting all 48 row/series forms
80
Set class and label
All pitch class sets related by transposition or inversion
The charrrtttt
LABELED WITH PRIME FORM Intervals (0XX)
81
Prime form
(0 then the interval between 1/2 and 2/3 ordered smallest to largest)
For set class
82
How make prime form
Transpose to start on c, subtract that number of semitones from “pre prime for” all numbers, will start on 0. check the charrrttt
83
Three ways to relate sets belonging to same class
Common tones, motivic transposition, and longer referential collections via some combinations of trichords from diatonic, hex, pent etc
84
How is sound of pitch class set determined
Interval classes
85
Invariance
Preservation of a collection of pitch classes when a 12 tone series is transposed and inverted
86
Combinatoriality
Combining a pitch class set with one or more transposed or inverted forms of itself or it’s compliment to create a collection of all 12 pitches
87
Aggregate
Collection of a 12 pitches
88
4 ways in which a series of three notes can be related
Inversion, transposition, retrograde, and retrograde inversion
89
Axis of symmetry
Also known as inversional axis
Centric tone or 2 a half step apart
90
Post tonal modulation
Shift from one axis of symmetry to another
91
Pitch symmetry
Notes that are inversional partners balance around central pitch (axis of symmetry)
92
Pitch class symmetry
Notes that are inversional partners around inversional axis on pitch class clockface
93
Inversional symmetry
An arrangement of notes that have same intervals going up as coming down
94
Expanding wedge progression
Notes move symmetrically outward from central pitches
95
Contracting wedge progression
Notes move symmetrically inward towards centric pitches
96
Other symmetric progressions
Notes don’t HAVE to be consistent as long as every pitch is as far above centric as another below (inversional partner)
97
Inversional partner
Two pitches equal distant above and below centric pitches
98
