When I am inspired, as I often am, it is difficult to say if I adhere to the concept that I am not really "creative, and creativity is just a myth as David Bryne suggests in his book, How Music and Creativity Work.
 

It’s usually assumed that much Western medieval music was harmonically ‘simple’ (having few kew changes) because composers hadn’t yet evolved the use of complex harmonies. In this context there would be no need or desire to include complex harmonies, as they would have sounded horrible in such spaces. Creatively they did exactly the right thing. Presuming that there is such a thing as ‘progress’ when it comes to music, and that music is ‘better’ now than it used to be, is typical of the high self-regard of those who live in the present. It is a myth. Creativity doesn’t ‘improve.’

However - I am not sure I believe my inspiration is something fixed like a kernel of corn either, like seed corn such as Brahms suggests. David Bryne's work agrees with E. M. Harding's seminal work The Anatomy of Inspiration, though each approach the idea of creativity and inspiration from opposite positions. While Byrne seems to suggest that creativity is a myth and has no way of improving what music has existed, Harding suggests that the artist is only a shaper, a pruner of the original idea. Both seem to suggest that the artist, himself or herself, is not the creator of an original idea.

The true novelist, poet, musician, or artist is really a discoverer. Ideas — the theme of a plot, a poem, a picture, a theme of music — come to him as a gift. The idea, ‘the seed-corn’ as Brahms called it, he allows to develop naturally. There may come a point where it branches in one or many directions; he is free at this point to follow one or other. And it is here and here only that the judgment or choice of the true artist may legitimately be exercised. In fact the artist is in much the same position as a gardener growing prize rose trees, who in order to produce beautiful roses lops off unwanted shoots and suckers.

Today, and yes tomorrow I might change my mind, but for today, I believe that inspiration comes either from the artist or from God. While we humans might be vehicles for art, I do think through free will we make decisions that 'create' the art; create beyond the point of shaping a phrase of music or dance. I have listened and witnessed to many performances of the same exact work and something is missing that makes it magically art. The performer has to bring something more than the shape of foot, the notes music, the turn of a phrase. It artist brings an intangible that is yes created for a moment, fleeting as it might be. Watch the video below and maybe it might convey what I am attempting to say.
