This work is the third of several built of internally invertible all-interval
dodecaphonic chords -- Flipidodes, as I've called them and titled the
group's opening piece. Last Breath, isolating component hexachords,
was the second. Below are performance hints for the present work.
"Putting in order" here is of course ultimately a hopeless task, since --
defying each phrase's surely predictable fifth bar -- registral ordering
among its first four never repeats. The challenge is to stay not thrown.
"Indecision" is to be embodied within the full-bar slurs, each arbitrarily
in either cresc. or dimin., and in accel. or ritard., as the players see fit.
Non-full-slurred bars instead fix on one (same) dynamic and tempo.
These are Flipidodes' highlighted tetrachords grouped to yield per bar
the total chromatic. A gradual expansion of full-bar registral range is
paralleled in metronome settings, whose performance value depends
less on precise matching than on conveying proportional differences.
