Sequences Flashcards
1
Q
sequences
A
- popular compositional technique
- repetition of an idea or pattern that is the same or similar
- large motives can be called a sequence pattern, but it is a sequence just the same
- the rhythm/interval pattern stays the same but the pitches move to a new set

Q
types of sequences
A
- Melodic Sequence: repetitions that begin on different pitches
- the melody is the same in terms of rhythms and intervals but is has a new starting pitch
- there is an interval indication for the soprano and bass interval. that term is called Linear intervallic pattern (LIP)
- – means that even though the starting note may change, the soprano-bass interval does not
- Harmonic Sequence: The function of the harmonies also gets repeated. they move in a predictable pattern
- relationship stay the same relative to themselves, even though the pitches change
- an example of a harmonic pattern is root movement of fifths
- – D-G-C-F-Bb
- — down a 5th up a 4th
- we can further clarify the type of sequence by noticing how strictly is it transposed
- Diatonic Sequence: sequence that stays within the key signature. restates the same generic intervals but allows for quality shifts )M/m 3rd) etc.
- same ideas, but the key signature dictates the quality of intervals and allows them to change
- Chromatic Sequence: repeats the idea with the identical specific interval size. basically transposition
- since they move around so strictly with the intervals, it sounds like it is changing keys

Q
how to analyze and identify sequences
A
- you need to identify:
- what type of motive is the pattern based on
- – melodic, harmonic, etc.
- interval of restatement
- – first note to first note
- – finding that intervallic relationship
- – moving down or up?
- if motive is transposed, the interval should be indivated
- – this is known as the level of transposition
- — “we are moving it by ___ down”
- — space is filled in by P5, m3, etc.

Q
sequences take place not just in music but in art and math as well, and can best be summarized as ________________
A
- predictable patterns
5
Q
a ________ sequence is repetition of the material at different pitch levels
A
- melodic
6
Q
although they can alternate direction, sequences tend to like to go either up or down
A
- true
7
Q
a _________ sequence means the repeated material stays within the given key
A
- diatonic
8
Q
a ______________ sequence means the repeated material will be altered with accidentals to retain an exact pattern
A
- chromatic
9
Q
how fare a pattern moves every time it restates itself is called the _________
A
- level of transposition
