For a primitive, ancient instrument, it is remarkably evocative. People have heard its sound as a wake-up call ... a lamentation ... the cries of a woman in childbirth ... a way to confuse Satan ... a warning ... a call to war ... the sound of the human soul ....
The physical part of blowing a shofar is relatively easy. I run to ensure I have good wind, I practice a few minutes a day to build control and toughen my embouchure.
Studying the laws, getting my intentions in order is a little more challenging. There are as many ways to blow incorrectly as correctly.
The spiritual part is hardest. I find I need the help of everyone in the room to break through the roof & send our prayer to heaven.
