Tony knows I keep talking about the pianist Ethan Iverson and his stuff. I just wanted to put a link to his blog he has, because it is an enormous wealth of historical and theoretical information that I find very accessible (and applicable to vibraphone). The link I attached is a collection of some miscellaneous information Ethan wrote up for his students at NEC. Specifically check out his series of reharmonizations of "All the Things You Are" about 2/3 down the page (there's a playback button under the sheet music). It's a cool way to think and practice!
