AWARENESS IGNITES ACTION. âAs an educator in the field of microfinance, it is rare to find those opportunities that can bring your students closer to the action before they join the professional world. âI felt that my Human Connections internship this summer was designed specially for me. This experience has transformed me as a person.
Karst Cave, China. Photograph by Raymond Gehman. Looking like the set of a science fiction movie, China's Reed Flute Cave is bathed in purple-blue light. Created by an underground river more than a half million years ago, this highly accessible karst formation is one of the region's most popular tourist attractions.
The Flute. The flute is made in the form of an open cylindrical air column about 66 cm long. Its fundamental pitch is middle C (C4) and it has a range of about three octaves to C7. Sound is produced from a flute by blowing onto a sharp edge, causing air enclosed in a tube to vibrate. The flute as shown above is a transverse or side-blown flute. The modern flute was developed by Theobald Boehm who experimented with it from 1832 to 1847, desiring to give it a bigger tone. He finally produced a parabolic (bowl-shaped) head joint attached to a cylindrical body with open-standing keys and finger pads to cover large finger holes.
