Congratulations!  Your show idea has been selected to air a pilot, but first you must submit the Theme Music and record a voice over of one scene.  You can use either GarageBand or Reason to create the theme music for your show and use GarageBand with the built in microphone on your computer to record your voice over.  You can work alone or in a group of 2 or 3.  Both your theme song and voice over should be between 1 and 2 minutes in length.
