Was thinking about this today and wanted to know your thoughts?
Is it just someone who can improvise over chords?
Is it someone who knows some section of the “jazz canon” (tunes from a certain era of jazz)
Is it someone who plays “the language” in their solo?
Is it someone who can swing?
Some might say it’s all of these out together however sometimes one or two of these are missing or one of these points seems to be a min focus over all of the others?
I don’t think you have to have ALL of the above but I reckon most of these need to be in there somewhere. What am I missing?
