I guess/assume that really good jazzers will do that eventually anyway, that they won't necessarily be thinking, "oooh, such-and-such a chord, this would sound good", but is it bad to do that in the short term without necessarily knowing more than the basics behind it as long as you know what sounds OK?? Even if it's mostly instinct and not because you know that such-and-such a scale would be a good improv starting point from that chord???
I ask because often when I've said to people I'm trying to learn jazz, I get told to go learn all the chords and the scales etc. Scales are fine, and I have enjoyed learning those for the flute grade 1 and extending the patterns I have learned into all 12 notes of the scale, but although I basically understand how chords work I have always found them difficult to recognise and know instantly, so when I'm improvising, I'll tend to go with instinct and what sounds good rather than knowing which scale-y bits go with which chords etc...
Naturally I'm keen to keep trying and keep extending my knowledge, but I wondered if it's actually such a bad thing to play by ear and instinct not knowledge??
I hope this makes sense...
