halacha - How to blow a t'rua


How does one effect a t'rua when blowing a shofar on Rosh Hashana? The airflow must be stopped and started repeatedly in a short time, but it can, I suppose, be stopped either



  • at the glottis,

  • at the narrow end of the shofar (by blocking it with the tongue), or

  • anywhere in between (say, by effecting a velar stop)


— or, indeed, not by blocking the flow of air but simply



  • by repeatedly pausing exhalation with the diaphragm.



Is/are any of these mandated/barred by halacha? Which is/are commonly used or not used, and why?



Answer



The sefer "Teka BeShofar" says that there are two methods for producing a teruah: "The common way," and "the simple way."


The Common Way: Air stream is held steady, and the sounds are formed by moving the tongue in and out of the shofar's opening. This is the most natural way, but it has two drawbacks: 1) Most people cannot do this fast enough to form the sounds properly; 2) It runs a serious risk of filling the shofar with spittle.


The Simple Way: Tongue never comes near the shofar. Rather, continuously strike the tongue against the roof of the mouth, as if to make a "Tee" or "Too" sound. The Syrian teruah has minimal break between the sounds, and is produced by using "li" instead of "tee". [The Yekkishe teruah (Frankfurt-on-Main) is warbled, with no break at all, and the modulation is controlled from the lungs. Very difficult to do without experience.]
