This triplet-based exercise is a great test of your independence between limbs. Triplets are constantly trading off between two limbs while the other two limbs are keeping steady quarter notes.
Measures 1-2: triplets in hands (3 notes each), quarter notes in feet
Measures 3-4: triplets in feet (3 notes each), quarter notes in hands
Measure 5-6: triplets in right hand and left foot (3 notes each), quarter notes in right foot and left hand
Measures 7-8: triplets in right foot and left hand (3 notes each), quarter notes in right hand and left foot
Measures 9-16: repeats the previous patterns with triplets alternating single strokes between limbs
Measures 17-18: a “tag” ending to wrap it up
Measures 19-36: the entire exercise repeats with the left side leading instead of the right
A lot of combinations are covered here. Have fun with this one. Check back in two weeks for Triplet Limb Independence #2!
