What a wonderful coaching weekend my Women’s Barbershop chorus just had with Barry Towner! And although he’s a primarily a presentation coach, he had some very exciting sound techniques.
The secret to this particular trick is not simply having the Basses let ‘er rip. The big secret is holding them back.
As Barry explained it, in the last few bars, as everyone else is crescendoing, we keep the Basses held back to about a 6 out of 10 (mf). We hit the last chord, and the Basses let out the clutch and come roaring past everyone. (At this point we ditch the car metaphor, because what we now have is a freight train)
Your audience will be gasping from the sheer thrill of the ride!
