Drift

This one is about testing the crescendo and decrescendo technique, and also drifting up by the 53rd root of 2 (one step in 53 tone equal temperament). Actual from 0, to 1, to 2, to 1, back to 0 for each measure. So three steps.

Arpeggios in Opposite Directions

I changed the finger piano envelope to something like that chart, and then fed each note of some opposite direction arpeggios through it.

More Variations in the Variability

The piece offers each part a variety of measures to choose from. Sometimes I push one of the instruments to keep choosing the same measure, sometimes to try very hard not to choose the same one. Or it can sequence through them in a series. Variability is set for each instrument to a number from 0 (never pick the same thing again) to 32 (always pick the same thing again). The higher the number, the more likely it will pick the same measure twice in a row. In this section I vary the variability a bit.

At the end of the bridge, we hear G, then a 53rd tone step up, then another, and back down again. I can't even hear the change.

I had an error in the cello part, not reseting the key before going off into the distance. I regret the error.

Settling down

Circling around the fourths in minor keys, then find the major key to state the theme. Still needs better dynamics. Later.

More Aimless Wandering about the Circle of Fourths

How aimless? How's this:

17 39 08 30 52 21 43 12 34 03 25
47 16 38 07 29 51 20 42 11 33 02
24 46 15 37 06 28 50 19 41 10 32
Those are the keys in which it wanders, spending only a measure in each. In 53 tone equal temperament, those are all 22 steps, or a perfect fourth apart. You can see we get close to the start, when it hits 16, then 38, which is like the first two chords 17 & 39. After a short while the repetitive chord changes just leave one with a feeling of never ending change. Not a pleasant feeling in my mind.

Cycle of Fourths - Misses by One

A cycle of fourths looks like the chart on the right.

In 53-tone to the octave equal temperament, 22 steps makes a perfect fourth. Start on E, and see what happens after 13 modulations. Instead of coming back to 17, you end up on 16. So what do you do when you don't come our right? I slide up by one and make up the difference. Otherwise I suppose I could go around again. How many would I have to cycle through? 54. Naturally.

Lots more trills in the flute and cello. This is going round a circle of fifths, but keeps missing the destination by one out of 53.

Chords based on fourths

Instead of triads based on the 4:5:6 and the 7:9:11, these are based on 5:7:9, 7:12:16, and other fourth based triads.
