In Western music and music theory, augmentation (from Late Latin augmentare, to increase) is the lengthening of a note or the widening of an interval.. Augmentation is a compositional device where a melody, theme or motif is presented in longer note-values than were previously used.
This is often interpreted as a quartal hexachord consisting of an augmented fourth, diminished fourth, augmented fourth, and two perfect fourths.The chord is related to other pitch collections, such as being a hexatonic subset of the overtone scale, also known in jazz circles as the Lydian dominant scale, lacking the perfect fifth.

Each sruti or micro tonal interval has a definite character; the names manda, candovati, dayavati, ranjani, raudri, krodha, ugra or khsobhini denote their emotional quality which dwells in combination or singly in the notes of the modal scale: thus, dayavati, ranjani and ratika dwell in the gandhara and each of the notes ( swara) of the scale in its turn has its own kind of expression and ...
The augmented scale: 0 3 4 7 8 11 (Root, minor 3rd, major 3rd, 5th, augmented 5th, major 7th, or minor 3rd, semitone, minor 3rd, semitone, minor 3rd, semitone) may appear to be an inexplicable omission on Messiaen's part. It is a symmetrical scale used frequently by modern jazz improvisers.
