The idea for this piece is the same idea present in Arnold Schoenberg's "Farben" ("colors" in german), a piece for orchestra in which a single chord is held during the whole movement while changing the  instruments that are playing it. Likewise, in my piece you have a simple  sequence of 2 chords repeated over and over while changing orchestration (color).
