Fiducial Epoch is about time, and the complex, often arbitrary way that we tend to think of, measure,
and experience it. The term “fiducial epoch” simply means a mutually decided upon point of reference.
In western culture, for example, the birth of Christ is often considered to be the fiducial epoch for
measuring the passage of years. This date is generally known to be incorrect or inaccurate, yet it
remains, simply because our measurement of time is largely arbitrary.

The structure of the piece is based on the lunisolar calendar. This is a calendar traditionally used in a
variety of cultures to track religious holidays. It attempts to align with both the movement of the sun
through equinoxes, as our Gregorian calendar does, and the phases of the moon. Most lunisolar
calendars have 12 months and insert an intercalary “leap” month every three years. The idea of getting
an extra month every three years is alluring. No one has enough time for everything in their lives
anymore. A special, extra month feels like a magical idea.

The twelve main movements of the piece are cyclically organized in “seasons” based on character and
playing technique. The piece may begin at any point within these twelve movements and is played until
that point is reached again. An optional thirteenth movement may be also be inserted between any two
regular movements of the piece.

The arbitrariness of time occurs in more detailed levels of the piece as well. The overall length of certain
sections of the piece, and the content of the electronics are both determined by the player.
