The use of the throat muscles is perhaps the hardest thing for Yolŋu to explain and teach, and may just need to be developed over time. The air flow of the tongue motions is increased, and the sound is deepened by support from the throat. Muscles of the throat control pockets of air and provide extra pressure and a sort of extra “wobble” to the sound which compliments the “dhirrl” motion. Yolŋu do not teach this as they do tongue motions, but merely hear it and know it is part of the desired sound that is achieved through practice of the proper style.
