3 instruments in total,

Piano represents Marianne, Bass represents Kody,

so who does the drum set represent?

Drums are no longer a symbol of mankind, but time,

the one that can be moved forward or backward by a certain function.

and the "time" stick between the piano and bass, seemingly tacit,

but there’ll always be some uncoordinated and additional “rhythmic grain”,

which interfered with the stability of spatial dimension where these two human live.
