Description

Tuning fork S - 227.43 Hz Moon, sidereal

Sidereal month

A lunar orbit lasts 27.32 days in relation to the fixed stars, called a sidereal month (from the Latin sidus 'star').

This is how the sidereal month differs from the synodic month: If the sun and moon are in front of a certain fixed star and the moon is there again after a sidereal orbit, the sun has moved one zodiac sign further. It will take another 2 1/4 days until the moon is close to the sun again and has completed the synodic orbit (29.53 days).

Once every 27.32 days, 29 octaves higher is a tone frequency of 227.43 Hz and another 41 octaves higher is the color light frequency yellow. More information about the sidereal moon tone can be found >here.


Tuning fork length: 15.5 cm
