Mitchell is renowned for her harmony, and Whitesell has studied the chord progression of every song within the period of his book, stratifying her practice into five categories: Modality; Polymodality
; Chromaticism; Polytonality; and Strict Pedal Points.
In discussing polymodality
and the creation of the work As I crossed a bridge of dreams (1975), she draws out elements from her own experiences as a female composer in a time and place when these contexts were being challenged and reshaped.
He was a pioneer of polytonality and polymodality
from the early 1900s onwards, besides being a master contrapuntist whose idol was J.
As seen in Figure 2, the combined data set is not well described by parametric distributions, and there is a suggestion of polymodality
. These data are therefore described as an empirical distribution, with minimum and maximum values chosen as mean - 2 SD and mean + 2.5 SD, respectively.
We are currently witnessing the appearance of a whole range of new technologies and concepts: bicontinuity, hyper-branching, ceramers, structured particles, hybrids, hydrosols, interpenetrating networks, polymer blends, liquid crystals, nanopigments, nanocapsules, nanocomposites, nanotechnology in general, phase separation, polymodality
, self-assembling, smart coatings, self-repairing coatings, etc.
The flavour of the ensuing chapters can be gleaned from their titles: 'Some General Aspects of Technique', 'Tonality and Tonal Structures', 'A New Aesthetic: Symmetry as a Basis of Structure', 'Scales: their Origins and Application', 'Bichords, Bitonality, and Polymodality
', 'Constructional Principles', 'Sonata Forms', 'Sets and Other Nontonal Techniques'.
There is also discussion on layering textures through the use of bichords, bitonality, and polymodality
, often closely related to folk elements.
