This version of the Music Monsters web site has no embedded sounds. You may like to try the version
in which the buttons on the left play the notes of a scale as you point to each in turn, and there are more sounds on the 'Games' page.
Some Browsers detect errors when trying to play the embedded sounds, and if this is a problem for you, then
please stay with this sounds free version of the of the Music Monsters web site.
