Theme: Pause is a vacant moment of anticipation, it freezes time. Not moving in either direction. Pause makes sense only if it is re-pressed or it’s companions are pressed. Nothing stay paused too long.  Play followed by Pause gets smoothing connection, the beats where stopped are continued. Stop followed by Pause is a pack-up sign. Either Rewind or Fast forward followed by Pause is a potential dynamic pace to resume, anytime.
