Frequencies associated with metrical accents and contour accents did not differ between the two melodies; the position of tonal pitch classes did differ, so each melody has its own column. Strong metrical accents occur at positions 1 and 3 in each bar, and strong tonal pitch classes include the tonic, third, and fifth.
