“Mood mosaic” is not a legitimate art term, but a commercial gimmick using alliteration (repeated consonant sounds) and metaphor to sound fancy. It is nothing more than a collection (like a tile mosaic) of various artists onto an LP that purports to capture a “mood” or a subgenre of musical style (cop themes, travel music, 60's sounds, etc.), to play in order to set a mood or atmosphere—a “mosaic” of tunes whose only similarity is that they set an obvious mood—usually sensuality or seductiveness, occasionally something a little loftier—thoughtfulness or somberness. Think of the many collections of “Adagio” pieces by classical composers from many centuries and countries—they are all slow, low-keyed, melodic pieces suitable for studying or meditation. Anything can be called a “mosaic” if the small pieces form a larger surface design; it is merely a metaphor: “these musical selections, played together, form a mosaic of sound that sets a mood." The same metaphor could be used to label a fine art display--"These pictures form a mosaic of Parisian city life."
Thank you so much!!!!!!!!!!
