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:
“An ... important antidote to American democracy is American gerontocracy. The positions of eminence and authority in Congress are allotted in accordance with length of service, regardless of quality. Superficial observers have long criticized the United States for making a fetish of youth. This is unfair. Uniquely among modern organs of public and private administration, its national legislature rewards senility.”
—John Kenneth Galbraith (b. 1908)
“He maintained that the case was lost or won by the time the final juror had been sworn in; his summation was set in his mind before the first witness was called. It was all in the orchestration, he claimed: in knowing how and where to pitch each and every particular argument; who to intimidate; who to trust, who to flatter and court; who to challenge; when to underplay and exactly when to let out all the stops.”
—Dorothy Uhnak (b. 1933)
“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 (1905–1976)
