G and A are the names of the corresponding musical pitch (A, B, C, D, E, F, G). In this case the "A" is actually "A2" - a pitch two octaves below (1/4 frequency) A4 (also called A above middle C). A4 = 440Hz is the tuning standard that has been in use by the music industry for nearly the last century. But exactly how the other musical pitch names corresponds to a frequency is a surprisingly complex subject.
