What is G6?
G6 is the G in octave 6 — the 71st key of the 88 on a full-size piano, counted from the bottom. In standard tuning it sounds at 1567.98 Hz. It sits 31 half-steps above middle C (C4).
To find it, locate any group of two black keys: the white key just to their left is a C. Count up from middle C (C4) 2 octaves to reach octave 6, then step to G.
Every octave doubles the frequency: the G one octave up sounds at 3135.96 Hz and the one below at 783.99 Hz. The same piano key can be written as G, F##, Abb depending on the musical context — same sound, different spelling.
