I notice that a lot of people recommend playing a G root position dominant 7th chord in the left hand with the fingers 5, 3, 2, 1. But to me, 5, 4, 2, 1 is more comfortable.
Is it considered "bad" practice to play root position dominant 7th chords this way? Is there a reason the fingerings 5, 3, 2, 1 seem to be played more often than 5, 4, 2, 1?
