CHAPTER VI
THE BRASSWIND FAMILY
The horn; the trumpet; the trombone; the bass tuba.
THE HORN
Look at the golden horn with its open bell gleaming like a big yellow flower!
First notice the large bell that spreads out to a diameter of about twelve inches. Then notice that there is a tube that holds the funnel-shaped mouthpiece. If this long brass tube were straightened out it would be over seven feet long!
This instrument is nothing but a long tube spirally coiled and ending in a bell.
