Culture is what gives history life and meaning to the facts. Within this context, I think our culture should be able to accept this expanded mana. The more important question is when do we accept this cultural expansion. I don't have the answer to this. I think one of the guidelines is that it does not have a commercial basis, that is, it should reflect the life, trials and joys of our people.
Hawaiian music is an example of cultural expansion.
Prior to the arrival of na haole, our music consisted of chants. When na haole arrived with new instruments and the three quarter time waltz tempo, we readily adopted it as a means of expanded cultural expression which has come to be known as Hawaiian music. What we cannot do is forget the evolution of the culture and its significance at that time in history. I hope this provides you some new insights.
