Patterns from the Game of Life
Part II: Rondo Infernale
for piano 4 hands
[3:00]

This volume is a second of three evolving music from Game of Life start- graph configurations.  It differs from Vol. I mainly in comprising a single relatively extended movement rather than multiple tiny ones, and in having keyboard texture wide/dense enough to need four hands for performance.

Its Game of Life graph sources, one for each of the Rondo's letter-named section groups, are as follows.  (For full information on any, access site ConwayLife.com and search on its name.)

Section   GOL Pattern Name       Discoverer           Year
A:            P61 Herschel Loop 2    Paul Callahan     1997
B:            Period-50 Glider Gun   Dean Hickerson  1996
C:            Mirage                          (?)                       (?)
D:            P48 Toad Hassler        Bill Gosper          1994

I will note here that, aside from the various applications of horizontal &/or vertical reflection, a technique of parameter swapping (X values become Ys and vice versa, i.e., exchanging pitch and time) has figured strongly. Section C', for example, is almost purely C itself rotated ninety degrees.

Re articulation: Notes within a slur are to be connected.  Notes outside a slur either before or after are to be audibly detached from it and from each other.  Where, as often occurs, a slur contains immediate note-repetition, connection must be effected via the damper pedal (without "smooth-over" between slurs).  There are no ties.

Re clusters: Where chords are stretch- &/or density-wise unmanageable, players are invited to hollow them out, so to avoid undue rolling - discretely, preserving dissonance as far as possible.
