UESTION VII. WHY THE ACCORDS IN MUSIC ARE SEPARATED INTO THREE.

QUESTION VIII. WHEREIN THE INTERVALS MELODIOUS DIFFER FROM THOSE THAT
ARE HARMONIC.

QUESTION IX. WHAT IS THE CAUSE OF ACCORD? AND ALSO, WHY, WHEN TWO
ACCORDANT STRINGS ARE TOUCHED TOGETHER, IS THE MELODY ASCRIBED TO THE

QUESTION XI. THAT WE CONTINUE NOT ALWAYS THE SAME, IN REGARD OF THE

Menelaus accepted the challenge, and the conditions were sworn to,
