How do get the music to sooth Cerberus on mythology island on Poptropica?

You go to the Temple of Apollo (is that what it's called?) and talk to the statue with a Lyre. Make sure you have an instrument from the vase in that temple.

Now click on the statue, pass her test, and she'll give you a music sheet. Memorize it, then play the music on the sheet to sooth him.

Hope this Helps!
