Slow Waltz
for chamber ensemble

to Liana, with love

Originally for piano (Composed in November 2023)
This arrangement was made in two-and-a-half hours on 9th December 2023. 

Slow Waltz, for ensemble (2023)

All That Jazz was composed as a piece for a cycle of Nocturnes which eventually became 'Facing the Night'. On reviewing the piece, I considered it to be sufficient as a standalone piece and as an exploration of highly chromatic jazz. Listen in for a quotation of a jazz standard!

All That Jazz, for MIDI (2021-22)

Another hypercanon piece.  

This time, from the mathematical perspective, beats get filled when their beat number equals the sum of a square, a positive cube and 6th power.  

Because the powers vary, the music keeps the counts on different instruments. 

The numbers to square get heard on the piano (with 1 the top key and then descending chromatically).

The numbers to cube get heard on pizzicato strings tuned in 19-TET, using an ascending scale that divides three octaves into 19 equal intervals which sound as nearly 10:9 rations.

The numbers to raise to the 6th power, never more than 4, map to a small gamut of tuned drums.

The complexities of the sets of sums of just two kinds of powers asserts itself as the irregular staggered entrances of the canon on the instrument associated with other power.  

If this is too much information for you, the bottom line is an intense listen which, white it has a hypersimple underlying concept, also feature a rather complex surface regardless, and because of the density of the beat numbers with a "yes" answer, intense but also unfamiliar syncopation. 

Big thank you to Peter Thoegersen, who literally wrote the book on polymicrotonal (and polytempic) music.  He's a genius and you should check out his music.  While his music and also his working methods are quite different than mine, he has opened me up to one of his great discoveries, namely that the listening mind can instinctively decouple the layers of a complex music according to the tuning systems girding each layer (at a given moment).  The effect is like passing to an experience in a higher dimension, akin to the discovery of perspective in visual art.   I'm not sure Peter would even count this as "poly" since two of the layers are 12TET and my treatment of 19TET avoids actual microintervals.  But I'd never have come to this way of projecting my ideas without his influence.

The doctors didn't know what was wrong with my lumbar area. They said it was a herniated disk. Later it was found to be a diabetic complication that ate the nerves away from my lumbar area. Only 0.000000000000000875% of the population get this. i am very lucky. 

piano collection 15b: Herniated Disks Much Better Now.

An early ditty from 2002, for piano solo. The second in the piano collection series. 

Peter Thoegersen - Piano Collection II a

This is my fourth symphony, and I am using new software that sounds better. The new software is not microtonal friendly, therefore, there will be two versions: standard and poly microtonal. This version is in 12tet and it is still highly polytempic. Each choir of the orchestra is moving separately in Fuxian contrapuntal motions, such as, contrary, parallel, similar and oblique, with respect to tempi changes in the choirs.

Another fact about this piece is that it uses many fragments of Gregorian chant from the Liber Usualis and is scattered throughout the single movement piece. The chants are of various lengths and are brief. The form could be considered a type of "variation" form; even if the chants are not literally repeated, they do act as a type of chaconne, over which the symphony plays and explores.

Symphony IV: melodiae perpetuae in polytempic polytonality

This is a composite of 12 tracks: 4 strings, 4 pianos, and 4 drumsets all in four different tempos and 4 different tunings. All instruments are playing the original Hypercube score! No added notes.
