Which Roman god is associated with the sun and music?

Apollo was the god associated with the sun and music in Roman tradition.

Apollo began as a Greek deity whom the Romans adopted with little change to his name. He was linked with music, poetry, prophecy, healing, and archery. His emblematic instrument was the lyre, and myths portray him as a divine musician who entertained the gods and inspired poets.

Apollo’s connection with the sun became especially strong in later Greek and Roman thought. He was sometimes identified with the sun god Sol, although Sol remained a distinct Roman deity in many contexts. This means Apollo was not originally Rome’s only or universal sun god, but “Apollo” is the standard answer for the combined association with music and solar imagery.

Apollo was the son of Jupiter’s Greek counterpart Zeus and the goddess Leto, and the twin brother of Diana, the Roman form of Artemis. That family connection helps distinguish him from Jupiter, Mercury, and Mars, who had different principal domains.
