The dictionary defines art as “The expression or application of creative skill and imagination, typically in a visual form such as painting, drawing or sculpture, producing works to be appreciated primarily for their beauty or emotional power.” I suspect that, at the least, poets, choreographers and musical composers, among many others, would consider that definition narrow and unnecessarily exclusive.
