Sorry, Mel.

I assumed you (and others) would know what I typed meant.
Mac did a great job explaining.

As Mac alluded to, chord voicings is an advancement (to me anyway) in the development of a person’s guitar playing.

A fretted instrument like guitar allows a person to play a chord in many different ways. There are the common ideas of inversions, also open chords, barre chords and different voicings at different positions on the neck.

Since I am not a good player at all (about a ‘2’ on a 1-to-4 scale) I have had to find many “shortcuts” and “tricks” to get things done.

So, the 3x0033 translates to notes in this order (from low to high): G-D-G-D-G.
I play it with my thumb wrapped around the top of the neck holding down the G note and touching the A string in order to mute it.

PS: Though I did come across this chord by myself, it is also the main chord used in GE Smith’s version of Steve Earle’s “I Ain’t Ever Satisfied.”
