Where is this Music Within Uldah?

[Atamos]

I've heard this music in Thanalan too like Richter.

That piece of music plays in the Thanalan zones both at dawn (8:00 AM Eorzea Time), and the first time you zone into the area during the day.

Posting for confirmation. I sat my character over night in Central Thalanan and as soon as the clock hit 6:00 AM Eorzean time, it played, followed by the day theme. It probably plays in all Thalanan zones surrounding Ul'dah, possibly Southern Thalanan as well. I don't think I have ever heard it play in Northern Thalanan.
