Why are drumsticks held differently in each hand?
In the matched grip each hand holds its stick in the same way, whereas in the traditional grip, each hand holds the stick differently. ... This allows the stick to move freely and bounce after striking a percussion instrument.
How can I improve my drumstick grips?
Curl your other three fingers onto the drum stick, wrapping your ring, little, and middle digits underneath it. Much like with your thumb, these fingers shouldn't grip too tightly. This hold enables advanced control of your drum sticks while letting them bounce back from the drum head.
