H. Christian Friedrich Ludwig Buschmann, born today in 1805, invented the Harmonica, back in the 1820s. It was a 4-inch cube thing with 15 notes, however many that is. In the background you can see 1820s Berlin, where he was busy.
Congratulations and many thanks, H. Buschmann, is what Rhinos all say.
You may already know this, but Rhinos can make a sound very much like a Harmonica, all on our own. It can be mistaken for a Wheeze.
