Excerpts from the cover notes (enclosed):
Born in St.Petersburg in 1893,Ivan Wyschnegradsky was a disciple of Scriabin. In 1918 he had an intense mystical experience that caused him to see the necessity of a musical expression in micro-tones. Because of the chaotic conditions in Russia at the time,he moved permanently to Paris in 1920, where he lived until his death in 1979.
His determination and courage in face of incredible difficulties and the neglect of the musical world seem almost superhuman.because of the problems in creating adequate instruments for microtones,he had almost no performances until 1937 when he adopted the solution of two or more conventional pianos tuned to different diapasons.
Aside from the two successful concerts in 1937 and in 1945 in Paris, there were few performances and no publications.Only recently has the world recognized the importance of both his compositions and his theoretical writings on microtonal composition.
Since his death the "Association Ivan Wyschnegradsky" in Paris under the presidency of Claude Ballif has produces concerts,recordings and publications devoted to his music. But the first long playing recording of his music was produced by McGill University Records (No.77002) in 1978. On that recording the LePage-Mather Duo plays Two Concert Etudes,Op.19,Two Fugues,Op.33 and Integrations,Op.49, all in quarter tones. The works in sixths of tones on the present disc received their premieres at McGill University's Pollack Concert Hall in Montreal on April 21,1983* and are recorded here for the first time.
In the 1950's Wyschnegradsky elaborated his ultimate system for organizing his "continuum of sound".
This system he called "les espaces non octaviants". They are cycles that repeat not at the octave but at a slightly smaller or larger interval.In the case of Dialogue a Trois the interval is the major seventh or 33 sixths of tones.This interval can be subdivided equally (11,11,11) in "perfect regular structure" (requiring 3 pianos), in "irregular structure one colour" (9,12,12) requiring one piano) or in irregular structure two colours" (10,11,12) (requiring two pianos). He associated each piano with a color.
In DIALOGUE A TROIS he also uses his system of "ultrachromaticism rythmique"; very subtle changes in tempo which are the counterpoint of the small intervallic differences.The musical language can be reduced in three elements (1) broken chords, (2) repeated notes or chords, (3) regular fluctuations between two chords.
COMPOSITION OP 46,NO 1 is a short work which uses a non-octaviant space of 17 thirds of a tone (one third of a tone less than an octave). It is subdivided into three intervals of 12,11 and 11 sixths.This system offers the possibility of 34 different positions of the cycle.
The subject of the FUGUE in OPUS 30, on this recording, starts with a minor sixth,each note of which alternately slides downwards in sixths of tones. Following the five voice exposition the fugue features an entry in augmentation, and entry with the inversion of the augmentation, a stretto and a coda in non-fugal style.
For its pitch organization, Bruce Mather's POEME DU DELIRE uses Wyschnegradsky's system of "non-octaviant spaces", modified to produce a scale of thirds and sixths of tones.
Formally, it is a mosaic of six different textures: 1-monody, 2-a slow melody accompanied by complex broken chords, 3-a chorale with chords of 3,5,8 and 11 notes, 4-a melody of moderate pace accompanied by solid chords, 5-trills and chromatic (semitone) scales accompanied by slowly broken chords, and 6-fast tremolos and ostinatos.
Poeme du Delire is dedicated to the memory of A.Scriabin and his disciple I.Wyschnegradsky
ASPECTS by Jack Behrens is comprised of a Prologue,six Episodes and a Postlude- each less than a minute long. It is,in intent, a work for one piano with enhanced pitch possibilities; that is, the work is not antiphonal, with one piano echoing or reflecting another.Against a static pitch centre the Prologue quietly explores the "feel" of microtonal possibilities; these are reaffirmed (with many octaves slightly enlarged) in the Postlude. In the body of the composition, microtones are sometimes used to "color" pitches (especially in the final prankish Episode) and are frequently treated as point of fluctuation (rather than steps) or as ingredients in clusters (Episode 1) in other instances spatial expansion (Episode 3) or interval expansion (Episode 5) is explored .Aspects is dedicated to Bruce Mather.
