Product details
The pitch material utilized in 'Chant d'augmentation' or 'Song of Augmentation' has various sources, with one being an augmented scale consisting of alternating minor third and minor second intervals. The augmented chord is also featured, at times with an added minor third (producing the set 0, 3, 4, 8), while other times superimposed with its major seventh transposition (0, 4, 8 combined with its t11 producing a symmetrical set or combinatory hexachord made up of alternating minor second and minor third intervals). The beginning of the piece also features augment chord harmonics, produced by a combination of keys depressed silently, the use of the sostenuto pedal, and augmented sonorities sounded below and above the silently depressed augmented/add sharp 9 chord. The sostenuto pedal is again used in bars 19 through to 24, but this time to create a sense of bitonality. Conventional tertian sonorities are also represented, with and without added notes, as well as mixed interval chords such as secundal chords, made up of alternating tritone and major third intervals (essentially complete 13th chords). 'Chant d'augmentation' also utilizes 'golden mean' or 'golden section' proportions. The fraction represented by this ideology is .618, and manifests itself in the piece with 'moment de réflexion' or 'moment of reflection' in bar 71, where the 'golden mean' is underscored with three seconds of silence.
