I've been thinking about this a lot lately since I'm new to playing with others. When jamming with a drummer, is it generally best to place fills at the same time as a drum fill? It seems like this would be the best time, otherwise there could potentially be too many fills in one "bar" of music, making it sound to busy and disorganized? Also, is there a general consensus among musicians as to which parts of a song are a good place for fills? I know this can vary wildly depending on type of music. Right now I'm playing some jazz/funk/soul stuff that generally has two sections, then starts over from the top. Would it be best to place fills at the end, to put an emphasis on returning to the top? Thanks!
