music class vocabulary
term | definition |
---|---|
motive (motif) | short melodic and/or rhythmic figure that RECURS throughout a composition or a section of a unifying element. |
sequence | the immediate restatement of a melodic motive or longer figure in the same instrumental or vocal part at a higher or lower pitch. |
sequence segment | each separate unit of a sequence. |
retrograde | backwards. |
sequence rule 1 | Sequence requires at least two segments. |
sequence rule 2 | Most sequences have no more than four segments. |
sequence rule 3 | Sequences usually have only one direction. |
sequence rule 4 | Sequence segments usually continue by the same interval distance. |
EXAMPLE for sequence rule 4 | If first segment starts on C, second segment starts on E, then remainder of segments will continue in thirds. |
real sequence | contains continuing segments that are an exact transposition of the first segment. (It usually has accidentals; it has the exact same numeric pattern as the first segment). |
tonal sequence | accommodates diatonic scale, so only diatonic notes of the scale are used. Transposition of the segments may not be exact. |
augmentation (of a sequence) | longer note lengths (length=value) |
diminution (of a sequence) | shorter note lengths |
inversion | if the original (or first segment) is ascending, then the inverted descends (and vice-versa). |
