The video above made me think of the Feast of Trumpets and the type of trumpet used in this traditional Jewish feast. I found the below video showing the four different notes that a shofar uses and I found some commentary on the way the shofar is used during the Feast of Trumpets.
“Tekiah – One blow that lasts 2-3 seconds
Shevarim – It’s supposed to be a “broken” tekiah, made by sounding three quick blasts.
Teruah – The alarm is made up of nine very quick pulses
Tekiah Gedolah – Meaning “Big Tekiah”, the Tokea blows the shofar for as long as possible, but at least 9 seconds. If more than one Tokea are sounding, they often compete to see who can last longer.
The sequence of calls on Rosh Hashanah is:
tekiah, shevarim-teruah, tekiah;
tekiah, shevarim, tekiah;
tekiah, teruah, tekia.
tekiah, shevarim-teruah, tekiah;
tekiah, shevarim, tekiah;
tekiah, teruah, tekia.
tekiah, shevarim-teruah, tekiah;
tekiah, shevarim, tekiah;
tekiah, teruah, tekia gedolah.
As you can see, each line starts and ends with a tekiah. Each “stanza” is sounded separately. Prayers are said, the first three lines are sounded, more prayers are said, the second three lines, etc. I don’t know if it’s uniform everywhere, buy my rabbi says each call separately. He calls tekiah, I sound it, he calls shevarim-teruah, I sound it, etc. ” ~ Mr. Weissensteinburg
Here is a link to why the shofar is blown and what it is suppose to symbolize.
