These are some of the ones I’m listening to now. I’ve been replacing the versions on the web each day as I try to refine the approach. Version 9 uses the following keys for a bridge.
In the following table, the first column is the number of times it is played. The second is the key, and the last the duration; 24 is 3 beats, 16 is two. This version uses more keys than the other two.
# Key dur
2 Fnmaj 24
4 D+maj 16
5 A+maj 24
4 F+maj 16
3 E-maj 24
6 Fnmin 16
8 A-min 24
6 Cnmin 16
4 D+min 24
4 Gnmin 16
4 Dbmin 24
4 Ebmin 16
5 Abmaj 24
7 Fnmaj 16
5 D+maj 24
1 A+maj 16
Version 10 looks like this. For some reason, he picked a lot of A Minor and C Minor. No idea why.
# Key dur
2 Abmaj 16
3 Fnmaj 24
2 D+maj 16
3 A+maj 24
3 F+maj 16
2 E-maj 24
9 Fnmin 16
16 A-min 24
10 Cnmin 16
6 D+min 24
4 Gnmin 16
2 Dbmin 24
3 Ebmin 16
3 Abmaj 24
3 Fnmaj 16
1 D+maj 24
Finally, here is what version 11 looks like. Far fewer alternatives made it into the final mix.
# Key dur
3 Ebmin 16
8 Abmaj 24
14 Fnmaj 16
19 D+maj 24
13 A+maj 16
7 F+maj 24
5 E-maj 16
2 Fnmin 24
1 A-min 16
The drunkard’s walk tends to make the results cluster near each other. In this case, around Db Minor, near the C Major of the primary key of the piece. It could just as easily cluster somewhere else. I don’t keep the history of where they clustered in versions 9 & 10.
