Silence is Golden
1) Sail around, doing whatever you please, until dawn.
2) As dawn approaches, you'll hear the classic "sunrise" theme. While this theme is playing, take out the Wind Waker and conduct the Ballad of Gales.
3) Warp to Windfall Island, then immediately head for land.
If done right, you will be at Windfall with no music whatsoever. The music doesn't come back, even as the sun rises high up in the sky (time does pass for a while, even though you're at a place where day doesn't change to night or vice-versa). To bring back the music, simply head into any building or leave the island. (Might also work at other places.)
