Pure Sine Wave Middle “C” Note One Hour

$1.50

Pure sine wave middle ‘C’ note for one hour good for tuning musical instruments.

Description

Middle C sine wave (261.63Hz) is an interesting note. Good for tuning musical instruments, the ‘middle’ is a music notation reference to its placement halfway between the treble and bass clefs. I always thought is was the exact middle note on an 88 key piano. It is a common reference in piano terminology as C major has no sharp or flat notes making it a popular key for beginning piano. The pure tone of the sine wave has no upper harmonics in its continuously smooth waveform. The is the one of several sine wave tones in a series on the channel. One Hour 320kbps mp3 format
