Hey there! Do you happen to like barbershop music? I'm a huge fan, and also a participant!
That's cool.  Is there an instrument you play?
Yes! I'm a horn player. I play the French Horn, but have also been trained in percussion instruments. How about you? 
I have only learned to play the snare drum, but that was only when I was young.
Oh, cool! I did marching percussion in high school. It's more challenging because you have to move while playing!
I can imagine.  Did you play the French horn in high school, too?
Yes, although I had to use a mellophone when I played in marching band since my school didn't want us carrying french horns around. It's like a bigger trumpet.
Oh, what's a mellophone?  Is it that thing that you put at the end of the wind instrument to "muffle" the sound?
Ah, you're thinking of something else! A mellophone looks just like a trumpet, but it's bigger and plays in the key of F or E, similar to a flugelhorn as well.
