Hi,

I recently build some chord progression and can't figure out its name. It's a higher G chord progression and I add a little note and I know that when I add a little note it will be go to something else but I don't know what it call exactly so what I need to learn next? I know some scale and familar with the note on the fret board.

Note: I'm a self taught guitarist and I'm sorry if my question and information I given is non sense to some of you but I'm sure you get the point.

Sorry, English is not my first language.

Chord build from scale does it mean that the scale I'm play in is actually the name of the chord? What something like chord that has number 7 or name Sus or any other weird name chord, How do you define it? Can you link me to a good learning resource beside justin guitar?

There's a difference between chords and scales

G major (scale) is G A B C D E F# G
the G major chord is G B D

The G major chord uses notes from the G major scale (separated by thirds: G to B is a third, and B to D is a third).
You can play the non-chord tones (A C E F#), but they have no function over G major the chord.
