Set of three Tuning Pipes: 256 Hz, 384 Hz,528 Hz, 1 Set

The Set of Three Tuning Pipes (256 Hz, 384 Hz, 528 Hz) by United Scientific groups three heat-treated aluminum alloy tuning pipes in one order, each laser etched with its frequency and hung from a wooden handle so it rings freely. United Scientific describes the pipes as louder and longer-sounding than traditional tuning forks. Physics teachers use the set to compare pitches, show how pipe length sets frequency, and demonstrate musical intervals to a whole class.
