An easier exercise we use is called honeycomb or 16th note grid. Its as follows:
\Rlrl Rlrl Rlrl Rlrl\rLrl rLrl rLrl rLrl\rlRl rlRl rlRl rlRl\rlrL rlrL rlrL rlrL\ x2
\Rlrl Rlrl rLrl rLrl\rlRl rlRl rlrL rlrL\ x2
\Rlrl rLrl rlRl rlrL\Rlrl rLrl rlRl rlrL\R
this is played with the repeats but no pauses in between them, staight through from the 1st note to the last ..those are all sixteenth notes. the lower case are taps the upper case are Accents. email me with any ??S
