A Homemade Horn

For awhile now, I've been fascinated by wind instruments, particularly the French horn. As mentioned in my previous post, I've always liked harmonics, and wind instruments rely on harmonics to operate, so naturally I wanted to learn to play. However, I had a problem: horns are expensive. So, I decided to make my own for about $10 at the hardware store.

I purchased 12' of .5" diameter tubing, a small copper pipe converter, and a set of funnels. These became the main tubing, mouthpiece, and bell of the horn, respectively. By simply sliding them into one another, I created a simple horn.

The interesting thing about this horn is that it's a natural horn: it can only play the overtone series, but no other notes. If the horn had valves to change the length of tubing, it could play notes outside of this series.
I have never played horn before, but I went ahead and made a video of me trying. Hopefully, I'll get better soon!
