These graphs represent various musical passages and movements in terms of their orchestration; they are tools for shifting our focus from pitch and harmony towards instrumental texture and effect. They are included in the book in black and white; this website presents them in color, which is clearer and more vivid.
Colors are used to represent the instruments of the orchestra: strings are different shades of green, while the winds are a variety of colors. Line thickness reflects dynamics: the louder the volume, the thicker the line. The color scheme is a nod to one aspect of eighteenth-century associations of instruments and colors, namely the notion that strings were more uniform and while wind instruments were more variegated. The specific colors chosen loosely reflect some instrument-color associations (such as scarlet trumpets), but were determined first and foremost by design and legibility.
