I can,t read music but can read and understand some chord names. What does C/G mean?

Hi,

C/G means that it is in the key of C but the lowest note is G. C would be played without the 6th string. C/G would be played with the fourth finger on the 6th string, 3rd fret. This is still C, but notated C/G to emphasize the fact that you are including the G (which is the way I always play C anyway).

Resting your thumb over the F# (6th string 2nd fret) whilst playing D, would I suspect be called D/F#.

These can also be referred to as split chords or inversions. On chordbook.com, the third inversion of C is C/G.

It makes a difference in some songs particularly when there is a running tune with the bass notes. Sometimes you will want to emphasize certain notes within a key.

thanks, I think.

...this method of describing a chord is called "slash chords", ie: CHORD-slash-BASS note, often associated with Nashville players.

If you need more help, or don't get what someone says, don't be ashamed to ask for more help.

P.S. C/G would be a C triad in second inversion. (Root position/first inversion/second inversion) is the system used for triads.
