For me, art is when the artist touches the collective heart of the audience. Art makes your heart pulse with passion.
I also believe that art is participatory, between the creator and the participant(s). There are no spectators in art.
Great art draws you in and it never lets go. It inspires you. It moves you. It changes you at your core.
Imagine if everyone approached their chosen craft as art. What a wonderful world it would be.
