Title: Technology, trumpets & tunes
Description: "Despite its title, this program actually covers all the wind instruments, including the pipe organ. It considers the way in which the technology of making instruments has affected the course of musical development, particularly the development of valves for trumpets and Boehm's system of woodwind keys. The program examines the subject of vibrations in tubes, the role of finger holes, and the components of tone quality. It concludes by putting a camera inside a large church organ to show what happens inside this marvelous combination of thousands of pipes, hundreds of yards of pneumatic tubing or electric cables, and countless valves or relays in response to the movements of the organist's hands and feet."--Container.
