How about marimba?

Modern marimba music calls for simultaneous use of between two and six mallets (most commonly two or four), granting the performer greater virtuosity and range. Multiple mallets are held in the same hand using any of a number of techniques or grips. For use of two mallets in each hand, the most common grips are the Burton grip (made popular by Gary Burton), the traditional grip (or "cross grip") and the Musser-Stevens grip (made popular by Leigh Howard Stevens). Each grip is perceived to have its own benefits and drawbacks. Choice of grip varies by region (Musser-Stevens grip and Burton grip are more popular in the United States, while traditional grip is more popular in Japan), by instrument (Burton grip is less likely to be used on marimba than on vibraphone) and by the taste of the individual performer.
