The brillophone is an instrument you make by cupping your hands and clapping them in front of your mouth. You form a small, circular opening with your lips, hold your breath, and open your throat as though you're going to swallow or yawn.

Air from the hole above your thumbs forcefully enters your mouth and creates an echo. You create different notes and tones by changing the shape of your mouth and lips.

I learned this from my dad, Henry Brill (1898-1965). A sales representative for a manufacturer of men's hosiery in real life, he was a prizewinning amateur ballroom dancer in Berlin in the 1920s and 1930s, as well as an amateur entertainer. Where he picked it up I'll never know.

My greatest musical and creative inspiration is jazz cornetist, pianist, and composer, Bix Beiderbecke (1903-1931).

Imagine my surprise when I received a voice mail message that someone by the name of Bix was signing up for my September 19, 2009 tour of Prospect Park in Brooklyn, and when I returned the call, that his last name was Beiderbeck!

Turns out this Bix is the great grandnephew of the musician—bright, friendly, creative (this Bix, who hails from Sweden, is a successful architect who designs science museums and other structures in the US), and with an enthusiasm that reminds me of the tone that characterizes the recently pubished letters of his great granduncle.

It was an honor and a pleasure to lead a tour with a member of this family, and even play a piece for Bix on the Brillophone, "Sorry," that his ancestor had recorded.
