IMAGERY

Mix imagery is important.  The overall width of the stereo field and how instruments are distributed within that area is an important mixing tool.  Likewise the space you create to put the vocal in (the reverb setting you will send the vocal to) is important not only in terms of defining the overall mix space but also in enhancing specific feelings in the vocal.

Music should always be discussed with subjective as well as technical terms.  Sometimes a visual description is better than a technical analysis.  Once when I was mixing I could not properly place a specific instrument to a client’s liking until he described a visual scene to me and told me to have the sound act like one of the elements in the scene.
