" You can have the perfect message, but it may fall on deaf ears when the listener is not prepared or open to listening.These listening " planes" were first introduced by the American composer Aaron Copland (1900-1990) as they pertain to music . . . 1. The Sensual Plane: You’re aware of the music, but not engaged enough to have an opinion or judge it.2. The Expressive Plane: You become more engaged by paying attention, finding meaning beyond the music, and noticing how it makes you feel.3. The Musical Plane: You listen to the music with complete presence, noticing the musical elements of melody, harmony, pitch, tempo, rhythm, and form. "
