Problems
The brass reeds in common pitchpipes are subject to work hardening with use, so they gradually change pitch. Because of this, replacement reed plates are sold. Carried in a pocket, a pipe will occasionally pick up small bits of lint which works its way into the narrow space around a reed. This usually requires disassembly of the pipe in order to clean the lint off the reed. To avoid this eventuality many users will use a small holster to carry the pipe.

Famous quotes containing the word problems:
“I conceive that the leading characteristic of the nineteenth century has been the rapid growth of the scientific spirit, the consequent application of scientific methods of investigation to all the problems with which the human mind is occupied, and the correlative rejection of traditional beliefs which have proved their incompetence to bear such investigation.”
—Thomas Henry Huxley (1825–95)
“Wittgenstein imagined that the philosopher was like a therapist whose task was to put problems finally to rest, and to cure us of being bewitched by them. So we are told to stop, to shut off lines of inquiry, not to find things puzzling nor to seek explanations. This is intellectual suicide.”
—Simon Blackburn (b. 1944)
“More than a decade after our fellow citizens began bedding down on the sidewalks, their problems continue to seem so intractable that we have begun to do psychologically what government has been incapable of doing programmatically. We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)
