I find that many ocarinas are expensive if not made out of plastic so I like to make my own out of Crayola clay. Whenever I make them, they always sound very quiet and the notes don't sound loud - they're too quiet. I've played around, the notes are in tune. I've tried blowing softer and blowing harder. I really want to make an ocarina that can atleast make proper notes or sounds! Please answer quickly because I need to play the song of time and save princess Zelda.
