Hello Again 8O
I think the key word is "familiarity"
put on a song's that you
know how play, blues, gospel, R&b, etc. then close your eye's to increase your sense of hearing and play. you will
miss the mark a few times but hang in there and let your ear's do the job.
Also while listening to song's and playing try and remember patterns that
are common to a particular to that style of music. Exp: 1-4-5- most common in blues or the funky open E with a two octave slap/pop, also
you could find your vocal key in relationship to the Bass.
Just try and let your ears do the work for you, it takes a little time
