I'm sure yall already seen the post for basic chords fingering I play in my RH. Well, here is the fingering I use when I play those same basic chords in my LH:
Fingerings For Basic Chords (LH)
First I will give you the key, then the chord name, then the inversion, then the letters that make up the chord, then the fingers used to play them. In case you don't know your fingers:
5 = pinky
4 = ring
3 = middle
2 = index
1 = thumb

Like I said at the beginning, these are the fingerings that I use personally. If u can use them, great. If you come up with your own, that's great too. Any questions feel free to ask me.
