I heard that if there is a chord written like
x/y then that means an
x chord with
y in the bass. This can be played by playing
x normally, but then playing the
y note on the 6th string, correct?
Then what about G/B? B on the 6th string is the same as the B on the 5th string 2nd fret. That note is already played in a G chord. So does that mean that all notes lower than that note are omitted?
Here is a list of ways to play G/B. The only one that makes sense to me is 7. 1 is very similar to 7, except instead of playing B on the second string D is played. Won't that sound different? How can these two be the same chord?
