Many of my favorite really complicated songs have these quintuplets in them (5 equally-spaced notes in the space of a quarter note), yet I can't seem to "feel" these 5-note subdivisions. I have no trouble listening to, say, Take 5 by Dave Brubeck and feeling that, but how on earth can I feel the 5-note divisions in the context of a 4/4 time signature? How do the really advanced players of these songs conceptualise this rhythm?
If the answer is just to practice it, that's okay, but ideally if anyone knows any helpful tips, that would be great.
