The shofar is a ram’s horn that is blown on the High Holidays, Rosh Hashanah and Yom Kippur. Blowing the shofar follows a specific pattern. It is composed of three sets of blasts, each consisting of three repetitions of three notes.
Each set is different from the other. The various notes of the shofar that are blown are:
teki’ah–one long blast
shevarim–three broken sounds
teru’ah‑-nine staccato notes.
The shofar blasts follow a prescribed pattern:
The final tekiah is prolonged (it is called teki’ah gedolah, a “great blast”). Some people have been known to watch the clock during the teki’ah gedolah and time how long it lasts. Trumpet players seem especially good at this one!
