G

G, 7th letter of the alphabet. It is a usual symbol for a voiced velar stop, as in the English go. It was originally a differentiated form of Greek gamma, which has C as its formal Roman correspondent. In musical notation G represents a note on the scale. In physics, G stands for the gravitational constant (see gravitation).
