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:
“The poverty of our century is unlike that of any other. It is not, as poverty was before, the result of natural scarcity, but of a set of priorities imposed upon the rest of the world by the rich. Consequently, the modern poor are not pitied ... but written off as trash. The twentieth-century consumer economy has produced the first culture for which a beggar is a reminder of nothing.”
—John Berger (b. 1926)
“Though I have locked my gate on them
I pity all the young,
I know what devils trade they learn
From those they live among,
Their drink, their pitch and toss by day,
Their robbery by night....”
—William Butler Yeats (18651939)
“What does headquarters think these guys came over here for, a sewing circle? They go up playing for keeps. Cops and robbers with rocks in the snowballs. Brass knuckles and lead pipes and a roughneck conviction they can lick any man in the world.”
—Dalton Trumbo (19051976)
