Subtracting, Leaving Out, A Fond Farewell

What makes a dance that dance? I mean, what makes it it and not something else? Yes, I know - a dance is a work of art that explores a subject using a specific set of movement phrases or structures to specific music with specific costumes, or not. But, what I mean is - how much can you remove and a dance still be that dance? We are finalizing the structure for our upcoming Clarice Smith Performing Arts Center show and I am wrestling with including our Falling Section or not. This section was inspired by Rachel Carson's The Edge of the Sea - an interesting, if overly detailed, look at the tidal zone of the Eastern Seaboard. It is a physical section with a strong athleticism to it - not so 'dancey'. But, for our upcoming show it doesn't fit in with the more etherial material of the other sections. I feel conflicted leaving it out since it has been central to the work since its beginning. The other sections that have been in each performance include H2O Trio, Christine's Solo w/ Bulking, Hurricane Solos, and some version of Drench. Additionally there are statistics about water always used as part of the sound score. Now, for this last performance, we aren't using the statistics nor the Hurricane Solos, and (I guess) the Falling Section. It would be interesting to see how much I could remove before My ocean is never blue stops being itself.
