The video presents two challenges: one in music and another in measure theory. The first challenge explores the harmony of musical notes based on the rationality of frequency ratios, while the second challenge involves covering rational numbers between zero and one with open intervals, ensuring the total length is less than one. The video connects these concepts, highlighting the surprising relationship between music and mathematics.
