A piece again in G major, or rather in E minor, and it is essentially based on three chords: Em - Cmaj - Am.

You know which chords appear on the steps of the G major scale, here again for everyone:

1st G major 2nd A minor 3rd B minor 4th C major 5th D major 6th E minor 7th F # minor 7-5

This again for everyone who deals with pop and jazz songs. It has become common for me lately that I do most of the songs in the keys of C - F - G. After a while you should be able to confidently handle the chords in these keys.

In the member area you can find more information about all three keys.
