This exercise has been tailored for different bass line sizes—2 players, 3 players, 4 players, or 5 players. (If you have a larger bass line, simply take the version for 5 players and have two players double one of the parts.)
It covers numerous combinations of sixteenth note triplet split patterns, a skill all bass lines must master. The constantly shifting patterns will keep everyone on their toes. I would recommend practicing each two-measure pattern (indicated by the double bar lines) separately at first. Play each two-measure pattern over and over until your whole section has it down. Once you have each pattern down smoothly, practice the entire exercise from start to finish.
When practicing, be careful to maintain correct note spacing. Usually players tend to err on the side of spacing the triplets too tightly (crushing them), and extra care must be taken to space each note evenly. Sometimes players overcompensate and spread the notes too widely, so be careful to avoid the opposite error as well. Use a metronome to help with pulse control. If possible, get someone with good timing to listen to the exercise and give feedback. If your line works it up, feel free to post a video and link to it in the comments section below.
Happy splitting!
