My recent and fantastic purchase of this musical instrument has made me an unwitting oppressor.  This ocarina is made to play loudly, filling the space you are playing in and matching the volume of other instruments without the need for amplification.  It also fills all four of the units in my house.  For some reason, Karl made a 30 minute video on this, which I have not watched in its entirety (actually I’m watching it now and it’s hilarious, but not as useful as the one I made).  Instead, I took two minutes and a straw to make the silencer in the video below.  Enjoy!
