I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

G (musical note)

From Wikipedia, the free encyclopedia

Sol, so, or G is the fifth note of the fixed-do solfège starting on C. As such it is the dominant, a perfect fifth above C or perfect fourth below C.

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle G (G4) note is approximately 391.995 Hz. See pitch for a discussion of historical variations in frequency.

It has enharmonic equivalents of F

double sharp (a diatonic semitone below G) and A
double flat
(a diatonic semitone above G).
