The visual metronome provides an effective visual tempo signal that is
easily discerned by a user without being dominating or harmful.
Preferably a user will position the metronome to one side of the center
of his expected line of site. The metronome visible within a user's
peripheral vision uses an inversing dominant pattern producing two visual
states. Each visual state is maintained for one beat of the beat per
minute rate set by a user. Each visual state includes a light region and
a dark region of similar size and a preferred dominant pattern includes a
four region checkerboard pattern.
