Meaning of Augmentation in Music
Augmentation in music refers to the lengthening of the time values of the notes in a melody. It is a technique used by composers to develop and vary a melody, adding dignity and impressiveness to the music. Composers often use augmentation to bring majesty or climax to the end of a section or piece. This lengthening of note lengths is called rhythmic augmentation.
For example, if a melody initially consists of quarter notes (crotchets) followed by a half note (minim), the same pitches can be repeated, but this time the lengths of the notes are doubled to become half notes (minims) and a whole note (semibreve). This demonstrates rhythmic augmentation in the melody.
Augmentation is the opposite of diminution, which involves shortening the time values of the notes in a melody.
Statement of a melody in longer note values, often twice as slow as the original.
