Four-mallet vibists usually play scalar linear passages much the same as two-mallet players, using one mallet from each hand (outside right and inside left for Burton grip), except that four-mallet players tend to make more use of double strokes, not only to avoid crossing hands, but also to minimize motion between the two bar rows. For example, an ascending E flat major scale could be played L-R-R-L-L-R-R-L, keeping the left hand on the "black" bars and the right hand on the "white". For linear passages with leaps, all four mallets are often used sequentially.
