From the db interview I posted Wednesday:
Do you take the credit for creating the four-mallet technique?
What I take credit for is popularizing it. There were plenty of examples of players using four mallets before I came along. In fact, there are some recordings from the 1930s with Red Norvo playing the xylophone that are pretty impressive. So, I got the credit because I got popular with it. Then, somebody started to call my way of holding the mallets the “Burton grip,” and it has stuck. And I wasn’t even the first one to use that way of holding the mallets.
