Play the song one of the Muses gave you on your reed pipe. This will make Cerberus fall asleep and you can get its whiskers.
Play the song on the instrument (I think it's a flute) and the dog will fall asleep. Then take the whiskers.
To get the whisker from cerberus on mythology, you have to play the pipe tune that you get from euterpre, the master of music, in the grove of temples. He will fall asleep so you can get it. This is for the mythology island .

I'm not exactly sure what notes, but in the music hall, there is a pot with flutes. Take one. I believe you need to talk to someone in there. You might have to give her something, but she'll give you the sheet music you need to play to put Cerberus go to sleep. I recommend writing it down so you won't have to try to remember it and keep looking back. I hope that helps.
