The G major scale

The key signature shows the sharp or flat notes in the scale. For G, you only have F sharp (F#). A simple way to identify the key if you are not familiar with reading sheet music is to figure out the sharp or flat note and go one half-step up. From F#, you take half-step to G. The rest of the notes in the scale are A, B, C, D, E, and F# at the top.

How to Identify G Major in Sheet Music

Another quick way to identify a song’s key is by listening to its final chord—many compositions end on the tonic chord, G major, if they are in this key.
