What is Poseidon's favorite musical instrument?

Poseidon, the Greek god of the sea, is often associated with the trident rather than a traditional musical instrument. However, if one were to attribute a musical instrument to him, it could be the lyre, which is linked to the mythology of the sea and often used in ancient Greek music. The lyre symbolizes harmony and the beauty of nature, resonating with Poseidon's dominion over the ocean and its depths.
