You cannot pass the satyrs with the reed pipe. Go to the Tree of Immortality (left of main street) and get the Golden Apple to begin your quest.
In mythology they are often associated with pipe playing, so I guess that would be a pipe.
The satyrs at the bridge (left) and Grove of Temples (right) prevent you from entering these areas until you know what you are looking for. Once you have the reed pipe from the Temple of Muses, and the starfish from the Museum of Olympus, you have done all you can do until you pass the Tree of Immortality, and have the scroll from Zeus

You can find it in Apollo's temple towards the right.
Climb the Tree of Immortality (use the bouncy mushrooms) and talk to the satyr at upper right. If you can recover his lost honey, he will help you get the Golden Apple. When you do, Zeus appears and offers you immortality if you return 5 sacred items that are scattered around the island.
