Messiaen also composed music in which the lowest, or fundamental, note is combined with higher notes or chords played much more quietly. These higher notes, far from being perceived as conventional harmony, function as harmonics that alter the timbre of the fundamental note like mixture stops on a pipe organ. An example is the song of the golden oriole in Le loriot of the Catalogue d'oiseaux for solo piano (Example 4).
