That helps understand it better. So is the bass usually the middle note in the right hand?
If you are playing a 2nd inversion chord, then yes it usually is. Example:
C major chord in 2nd inversion = G-C-E
root is C, if this is a 1 then the bass note is also C
C / G-C-E
I wouldn't bank on finding bass notes that way cuz it may not work out like that all the time. Sometimes the bass note ain't even found in the RH chord. In cases like that, the chord is split between both hands. Example:
F minor 7th chord = F-Ab-C-Eb
root is F, F is played in the bass, but Ab-C-Eb (Ab major chord) is played in the RH
F / Ab-C-Eb or F / C-Eb-Ab or F / Eb-Ab-C
