The patterns for this exercises where derived by transposing the Riqq exercises in this book into bass clef and applying double tongue phonetics to the beats outline. I highly recommend this book for anyone interested in Arabic rhythms. It is available through Earth Shaking Music in Atlanta GA.

"Borroloola, N.T. The second sample of didjeridu playing is by a woman,
Jemima Wimalu, who belongs to the Mara group at Roper River. Not only
is Jemima able to perform A-type accompaniments but, as she demonstrates
here, she is also proactised in playing didjeridu accompaniments of the
B-type. It will be noted in her demonstration that the rythmic patterning
incorperates an overblown or "upper" tone about an eleventh above the
'drone'; also that voiced effects, which mingle with the aerophonic or
blown tones of the didjeridu, enrich some of the lower tones. Other
characteristic B-type effects include (a) a commencing staccato sound
(other players may produce more than one, compare Band 3d); (b) a
following sustained and 'trilled' sound; and (c) a terminal 'upper'
tone.
Tempo is controlled by beating a stick against the didjeridu tube. Mouth
sounds demonstrated by Jemima are also accompanied by a beating stick.
