This would have been more relevant right after some comments from three
years ago, but I’ll go ahead and mention it to anyone else who is intrigued
by the grip used. The instrument is not what determines what grip you
should use, the music is. The Stevens (or the similar Musser) grip,
traditionally used on the marimba, is good for interval changes, but
inferior in terms of power. The Burton grip gets out a lot of sound but
can’t change intervals as easily. It’s about what the music calls for.
@xilometal Both grips are interchangable. I’ve seen musser grip (“marimba
grip”) on vibes, Burton grip (“vibes grip”) used on marimba, and some
in-between or completely strange grips used for both. It’s like drummers
using traditional grip in rock or matched in jazz. Not too common, but
still very valid.
