Modern Pitch Pipes
Although few look like a pipe, the pitch pipe name is still applied to any device used as a pitch reference. The most common type is a circular free reed aerophone. These are discs with the holes for the reeds around the perimeter and with marked openings for each note, into which the user blows. Inside the pipe, the air flows through a hole in a plate past the selected rectangular metal reed (usually brass). The airflow is modulated by the oscillating reed, then it resonates in an outer sounding chamber. In recent years, electronic pushbutton devices simulating chromatic pitch pipes have become available which are small enough to fit on key chains.

Famous quotes containing the words modern, pitch and/or pipes:
“There are moments when, faced with our lack of success, I wonder whether we are failures, proud but impotent. One thing reassures me as to our value: the boredom that afflicts us. It is the hall-mark of quality in modern men.”
—Edmond De Goncourt (1822–1896)
“People do not know the natural infirmity of their mind: it does nothing but ferret and quest, and keeps incessantly whirling around, building up and becoming entangled in its own work, like our silkworms, and is suffocated in it: a mouse in a pitch barrel.”
—Michel de Montaigne (1533–1592)
“Next, pipes are lit by those who smoke, and veils are donned by those who have them, and we hastily examine and dry our plants, anoint our faces and hands, and go to bed—and—the mosquitoes.”
—Henry David Thoreau (1817–1862)
