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.
