Example 7. Event-transformational analysis
of Bartók, Scherzo, measures 33–42
This passage’s characteristic gestures in the left-hand part are larger four-node networks of 4s and 7s, in which the 4 and -4 of the previous “wiggle” are now mediated by a 7 or -7. The notes in the right-hand accompaniment clearly derive by 7 from the prominent left-hand notes. The long green arrow indicates that the entire eight-bar group, measures 33–40, is transposed by the characteristic interval 7 (down in pitch a perfect fourth) to measures 41–48.
