Blowing Shofar – for yourself or on Mivtzoim – is a responsibility and mistakes (that are ma’akev) are at times made. After reviewing the halachos, one should have an expert listen to his Tekios, to make sure that it’s being done correctly.
To help you with perfecting your tekios, Rabbi Simcha Werner of Monsey, NY, composed a concise guide of the halachos of Shofar in both Hebrew and English.
Another reference is the tekios of London Shliach Rabbi Shmuel Lew who is known to carefully follow the Rebbe’s tekios:
A comprehensive card explains all the Halachos of how and why we blow the shofar, a must read for anyone who will be helping others to fulfill this Mitzvah.
