the pharynx
waldeyer's tonsillar ring is an anatomical term collectively describing the annular arrangement of lymphoid tissue in the pharynx. waldeyer's ring circumscribes the naso- and oropharynx, with some of its tonsillar tissue located above and some below the soft palate (and to the back of the oral cavity). it is believed that waldeyer's ring prevents the invasion of microorganisms from going into the air and food passages and this helps in the defense mechanism of the respiratory and alimentary systems.

the first drummers who started open-handed playing are musicians like billy cobham, lenny white, and dennis wilson, who started this way of playing in the 1960s and early 1970s either out of instinct (such as wilson, who was naturally left-handed and therefore felt more comfortable leading with that hand), or out of experimentation, finding the advantage of not having to cross one's hands over in complex fills or playing the hi-hats in the traditional manner. many proponents of the technique have also noted that the lack of a "roof" of another arm crossing over allows for the full range of the snare playing arm's stroke to be available, meaning that loud rimshots are more easily played. others have pointed out the added conservation of energy attained by not having to fully raise and cross one's lead hand when playing, for instance, between the hi-hats and ride in faster passages. as a result, many drummers in more extreme genres have adopted this technique. another advantage is a player's access to the floor tom while playing the hi-hats, a feat infamously difficult to pull off in the traditional technique without access to an auxiliary floor tom.
