organ pipe

In organ pipes the contained volume of air is caused to vibrate.

The following materials have been used for organ pipes:

Metals: lead, tin?, copper, and brass are the most common metals used. The lead and tin? are usually alloyed to produce what is termed "common metal" (where it has spots on cooling). Rarely antimony? is added for a hardening effect.

Tuning slides? are normally made of coke tin sheet, but aluminum? has been used also. Some aluminum? pipes have been made but these seem to be mostly experimental and have not been adopted by mainstream builders.

Woods: sugar pine (Pinus labertiana), western white pine (Pinus monticola), spruce (Pinus glabra), and redwood (Sequoia sempervirens) are the most common woods used. Hot horse hide glue is used to hold them together!

Cardboard and several forms of cardboard have also been used by amateurs and a few builders playing with a different material.
