Anyone can create fun sounds blowing into these ceramic or bamboo whistles made by artisans from the Peruvian Amazon. The ceramic whistles featuring colorful birds can make a fun sound on their own and make a trilling sound like a bird when filled with a little water. Ocarinas are traditional oval shaped whistles with 6 holes that produce a wide range of melodic sounds. Bamboo flutes have a slide that can pulled in and out to vary the tune.
