just putting this out there, sorry for my ignorance, but what is Bb/F ? can't find it anywhere..not on any chord charts..

Bb/F - 113331

thanks taco, thing is, thats the same as Bb whats this /F business? a lot of songs have Bb listed but also Bb/F if they were essentially the same chord why would they both be listed in the same song.. i got this one out of a pretty dumbed down songbook too so makes no sense... but anyway, i'll just improvise
cheers

As Taco said it's just 113331. The Bb is the chord name (B flat major), the F is the lowest or base note. If you play 113331, you're playing Bb/f. If youre playing at pos 6, youre playing Bb/Bb.

Hope this helps.
