Shofar Sounding

The blowing of the shofar is an injunction from Leviticus 23:24:

Speak unto the children of Israel, saying: In the seventh month, in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation.

The shofar blast is a wakeup call, as described by Maimonides:

“Arise you who are fast asleep, and awaken you who slumber, search your deeds, repent, and be mindful of your Creator . . . ”

Note that there is no description of how the horns will blast. So a variety of customs are followed by Jewish communities around the world.

There are 3 customary calls:

Tekiah – a long blast (varying lengths)
Shevarim – a wailing sound
Teruah – a broken trumpet sound
And, as the grand finale, Tekiah G’dolah.
