[Sneak Preview] Micro-Gigue, for Harpsichord [Negri, E19]


 A short Gigue, for Harpischord. Tuning is Negri (named after John Negri's «The Nineteen-Tone System as Ten Plus Nine». Interval, Journal of Music Research and Development, pp. 11–13 of Volume 5, Number 3, Winter 1986–1987), here rendered in 19-equal division of the octave.

Negri is a regular temperament such that: • Two generators make a tempered 7/6~8/7~15/13 • Three generators make a tempered 5/4~16/13 • Four generators make a tempered 4/3. This is the case in 19-equal division of the octave, and the generator is 2 steps out of 19, i.e 126.316 cents. This piece goes back and forth by a generator; more exactly, it modulates forth by a generator in part 1 (B to C), and it modulates back by a generator in part 2 (C to B, via D, E, F#). This is a sneak preview of a larger Gigue, as well as part of a larger «Negri Suite».

«Blue Canon», 3-in-1 for Baroque Oboe, Recorder, Violin, Bassoon, Continuo, tuned into Eagle 53.


 

«Blue Canon» is a 3-in-1 Canon in G for Oboe, Recorder, Violin, and Continuo, tuned into Eagle 53, a tuning devised by John O'Sullivan. Eagle 53 is normally centred around E; for this piece the same tuning centred around G has been preferred, though. The tuning has the following cent figures: G= 0 113.2 203.8 317 384.9 498.1 588.7 701.9 815.1 883 1018.9 1086.8; essentially, when centred around G, it consists in three pieces of the pyhtagorean chain of fifths: from Fb to Db, from C to A, from G# to E#. It can be used in a more diatonic fashion though, by avoiding the use of triads on F and A. Anyway, this example has been notated by means of the 12-edo customary notation.
