flute, pipe

In Bible times, pipes were musical instruments made of bone or wood with holes to allow the sound to come out. A flute was a kind of pipe.

Most pipes had reeds made out of a kind of thick grass that vibrated as air was blown over it.
A pipe without any reeds was often called a "flute."
A shepherd played a pipe to calm his flocks of sheep.
Pipes and flutes were used for playing sad or joyful music.
