I have two questions (detailed below).
So I've been watching a Frank Vignola video course on TrueFire.com and in a song called Tranquility he uses a chord which he has labelled C6/9 (he pronounces it as a "C 6 9 chord". Below is a screen shot of the music/tab notation:
Now at first I thought it must mean a "C Dominant 6th 9th" chord because that's typically how I've seen dominant chords written (e.g.
C7 is a C dominant 7th chord) and it wasn't written down as "Cmaj6/9" (which is what I would've expected).
But a quick cursory google reveals it is also known as a Cmaj6/9.
So my first first question is...
Why is it written like C6/9 when to me that confuses it with a dominant variety of chord?
Next I stumbled across the site http://www.jamplay.com/tools/guitar-chords/1-standard/3-c/4-69 which shows the C6/9 chord in different voicings. The one I was interested in (because it looked to match the one Frank Vignola had tabbed, but this one is on the 9th fret where as we're looking for the 2nd fret) was:
But this confused me because I've never heard of a 'set 3' voicing? It didn't look to be an inversion or a drop voicing as there is no
B note in the C6/9 chord.
So my second question is...
How and/or why are jamplay playing the same 'chord shape' but on a different fret, and yet both they and Frank Vignola are able to refer to it as the same chord? (unless the 'set 3 voicing' means something hence the difference in fret placement)
When I look at the notes that are being fingered from the 2nd fret perspective it looks like a 'rootless' Cmaj6 with an added 9th (we finger:
E, A, D, G).
Any help understanding this is appreciated.
