Art and Music inspired by Clive Bell's Chapter in Wartenberb

It is difficult to write a universal definition of art.  This is because their are so many types of art that what gives credit to one genre would have nothing to do with another.  You would need to look at numerous sub-genre's that all boil down to creativity and purpose.  


A simple painting of the sky is made up of different colors and painting techniques just like a song is made up of different instruments and styles.  Musical instruments are combined in order to convey the musicians intended emotion just like red and yellow paint would be combined to put an orange hugh in the painting of the sky to convey the painters intended emotion.   


As far as a the musician goes, a sight reader would read music and play it with what they were taught as far as what key and time signature to play in and a vocalist is no exception to this.  There are good pianists and guitarists and vocalist but what about the lyricist?  The lyrics could be taken as a poem combined with music to make a hybrid but can it not be argued that the lyrics are not a poem but instead words acting like notes that need to be read by the vocalist to convey the intentions of the writer just like a guitarist would play the notes they read?
