Micro-Fugue on Happy Birthday for Baroque Ensemble [Rameau OT]


 A short 5-part Micro-Fugue on "Happy Birthday" (a tune which is now in the public domain) in Bb, for Recorder, Oboe, Clarinet, Bassoon, Trombone.

Tuning is Rameau's TempĂ©rament Ordinarire (Ordinary Temperament), a circulating temperament generated by 7 meantone fifths (as large as 697 ¢) and five sharp fifths (as large as 704.2 ¢), then rounded to integer values. The cent figures of the tuning are: 101 ¢ 194 ¢ 295 ¢ 388 ¢ 496 ¢ 596 ¢ 697 ¢ 798 ¢ 891 ¢ 992 ¢ 1092 ¢ 1200 ¢.

Orwell Canon 3 in 1 upon a Ground for Baroque Oboe, Viola, Clarinet, and Viola da Gamba


 A 3-in-1 Canon upon a Ground for Baroque Oboe, Viola, Clarinet, and Viola da Gamba, in the Orwell tuning. The tuning is defined by the just perfect twelfth (3/1) being divided into 7 equal steps. One of these steps (as large as 271,71 ¢) represents 7/6; three represent 8/5. Alternately, one third of the «fifth harmonic» 5/1 also makes a good orwell generator, at ~ 12/7 or 928.77 ¢ = 1200 - 271,23 ¢.

Orwell is so named because 19 steps of 84edo, i.e. 19\84, is a possible generator; however, here Orwell has been implemented as 22edo generated by 5\22 = 272.727 cents. The Canon modulates by -1 Orwell (= -5/22 of an Octave) at the end of each of the 22 sections, and eventually comes back to the initial tonality of D.

Blue Golden Fugue, for Baroque Trumpet, Oboe, Clarinet, Bassoon [Microtonal, Golden 13-scale]

 


«Blue Golden Fugue» is a blues-flavoured fugue for Baroque Trumpet, Oboe, Clarinet, Bassoon. Tuning is a Golden 13-tone scale constructed in the following way: the Golden Ratio ~ 833.09 cents is iterated 13 times, landing to 10830.174 cents; this means 9 octaves plus 30.174 cents. This amount is uniformly distributed along the 9 octaves, so that we have a tempered 1203.353 ¢ octave. This system coincides with 92.5656 cET.

Orwell 2-5-1 Cadence


 

The 2-5-1 cadence, transformed into the Orwell tuning, defined by the just perfect twelfth (3/1) being divided into 7 equal steps. One of these steps (as large as 271,71 ¢) represents 7/6; three represent 8/5. Alternately, one third of the «fifth harmonic» 5/1 also makes a good orwell generator, at ~ 12/7 or 928.77 ¢ = 1200 - 271,23 ¢. Orwell is so named because 19 steps of 84edo, i.e. 19\84, is a possible generator; however, here Orwell has been implemented as 22edo generated by 5\22 = 272.727 cents. The 2-5-1 cadence has been transformed into the Orwell tuning by mapping each fifth (meant as a generator) into 5\22 = 272.727 cents, then rearranging the resulting notes in 22edo; 22-edo has been notated by using the customary linear notation.

Claudi Meneghin: Four Pieces in 15-equal Division of the Octave

We present four pieces by Claudi Meneghin, in 15-equal division of the octave, notated as usual in the following way:

  • B~C = 0 ¢
  • D = 240 ¢
  • E~F = 480 ¢
  • G = 720 ¢
  • A = 960 ¢
  • #/b = +/- 80 ¢

1) Cuckoo-Rag fugue


Cuckoo-Rag fugue is a one-minute fugue recorder, cor anglais, clarinet, bassoon, using a rag-like subject and the cuckoo tune as a countersubject. Tuning is 15edo (15 equal division of the octave), used in the following two ways: in the first part of the fugue, the entries of the fugue are each one at a fifth from the preceding one, whereas in the second part at a fourth.


2) Micro-Fugue on "Scotland the Brave"


A five-part microfugue  (in 15-equal division of the octave) on a theme derived from "Scotland the Brave", for Soprano & Alto Sax, Bassoon, Bass Clarinet, Suckbut, in the tonality of C. Each entry is a fourth higher (+480 ¢ in 15edo) than the preceding one, thus the fugue gets back to the initial tonality C after five entries (5*480 ¢ = 2400 ¢).


3) Tocada, for 2 Organs


A piece for 2 organs, in three movements (Preludi i Fugat, Chaconne “La Gamme”, Fugueta). 

    1. Preludi & Fugat
      The Preludi (Catalan for "Prelude") is made up by 5 sections, each at +720 cents from the preceding one. Each one, internally, sticks to the following modulation structure : 0, +400, +800, 0, +720;
      The Fugat (Catalan for "Fugato") is made up by 5 sections, each at +240 cents from the preceding one and ends on C (pedal).
    2. Chaconne “La Gamme” (French for "The Scale")
      This chromatic piece is made up by 15 sections, each at +80 cents from the preceding one (starts from F and ends to F), plus a Coda, made up by the following chord progression: (D,C,F,A) - (E,B,E,G#) ~ (240,0,480,880) - (400,1120,400,800)
    3. Fugueta (Catalan for "Little fugue") This fast movement is made up by five main sections obeying the following modulation rules:
      1st: C +720 +720 +720 +720 +720
      2nd: C +480 +480 +480 +480 +480
      3rd: C +240 +240 +240 +240 +240  (modified mirrored theme)
      4th: C +480 +240 +480 +240 +480 C
      5th: = 1st, with added bass in the beginning exposition
      Coda
