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.

Fixed some wrong notes in the cello part – oops

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

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.
