an E/b is a E chord with a B as bass root instead of the E
Yeah that's pretty much it, but you must remember the note beneath doesn't mean you remove the above note from the triad. E/B would still have an E note voiced somewhere in the chord. Also, the note outside the chord may not neccessarily be in that chord's normal triad to begin with (for instance E/C), in which cases I just generally play the normal chord and let the bass player fill in the additional note.
My favorite chord is basically the scale degrees 1 3 5 7 9 in any key, which I think would just be called a Major7 add 9, but I'm not sure.
The coolest voicing I've found for C Major7 add 9 is:
And blane doesn't pink floyd use that chord alot?
