Good art operates on many levels; cerebral, emotional, physical, transcendental, etc. However, I have found that each category of art has a general strength or primary mode of functioning.
1. Music is one of the most emotional art forms. Every chord seems to strum the heart strings and carry the listener along through intangible and undefinable peaks and valleys of emotional experience.
2. Poetry, and by that I mean words used for their own sake as art, is the most cerebral. The language is already known to the reader and they engage with their mind first. Even if their mind takes them almost immediately to a place of emotions and images they are starting with the intellectual structure of words.
3. Visual art is the most immediate art form in the sense that a viewer can take in the gestalt of a piece almost immediately. Even if it takes them hours to notice or discover something their eye can rove the entirety of a picture relatively rapidly. Visual art creates a self contained aesthetic experience that can fully immerse a properly prepared viewer almost at once.
These are certainly generalizations and I have left much unsaid, but what are your thoughts?
