First, listen to the the song "Gwen's Theme". This is the song that plays in the pre-searing Ascalon starter area. Pay attention to the flute at the 30 second mark.
Now the Queensdale music from GW2. Again, pay attention to the flute around the 30 second mark. (The video is black since I was just recording the audio. Also, my apologies for the sound quality.)
This sounds amazingly similar, not the same...more like similar themes. For me this is one of the many amazing ways GW2 ties into GW1, like listening to a familiar echo of the past.
