Chord "Deux" Jour Challenge: G#dim and Amaj7

The Chord "Deux" Jour Challenge means learning or expanding upon two chords per day. Check out the full list here.

Each chord map attempts to appeal to both beginners and intermediate/advanced guitarists and keyboardists. Simple chord shapes for beginners are provided with the following finger system:

1 index finger
2 middle finger
3 ring finger
4 little finger
o play open string
x do not play open string
( bar one finger over more than one string
T that rare occasion that I recommend you use your thumb to fret a note

Today's first chord is G-sharp diminished, or G#dim. By now, the chord map format should be familiar -- and hopefully understandable -- to beginners and advanced guitarists and keyboardists:

Guitarists, you'll notice that the open high E string has an (x), but the open B string has neither an (x) nor an (o). Keyboardists know this, and so should you: The B note is part of the G#dim chord.  You can play the open B string (if you can) or you can mute it.

Our second chord is A (major) major 7th, or Amaj7. Guitarists and keyboardists, the difference between a major-7th chord and a dominant-7th chord is one note. Compare Amaj7 with A7, and spot the difference:

In A7, the 7th note is G. In Amaj7, the 7th note is G#. That's the difference between a dominant-7th (i.e., major minor 7th) chord and a major-7th (i.e., major major 7th) chord.

Two more tomorrow. Cheers!
