protend
To hold out; to stretch forth.
obsolete, transitive
With his protended lance he makes defence.
To consciously experience in anticipation; to experience protention.
At the moment that the first beat is sounded, if the listener is to hear it as a division of a larger temporal unit, he or she must concretely protend the other beats of the bar; that is, the listener must experience, in the temporal "space" of the near future, three more beats while he or she is hearing the present beat in the now-point.
Where it comes from
Borrowed from Latin protendere, from pro (“before, forth”) + tendere (“to stretch”).
