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.

Here's a score of this piece.

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.

Sarabande, for Organ [22edo]

A short Sarabande for Organ in 22-edo.
