If you’ve ever played Gospel music thru a big PA in a huge acoustically treated auditorium, then you wouldn’t be asking this question.
One of my favourite musical memories was hitting Low C on the final note of the night in an 8,000 seat Entertainment Centre.
And that, to me, is where the low B string is more useful than anything. Music is meant to take both players and audiences on a journey. Want to end that journey (be it a song or the whole show) on an emotional high? Expand to the end. What I mean is this. You ever notice that the singer's "big note" usually comes near the end of a song? How many songs have you heard that involved screaming guitar solos while the singer is vamping at the end? (Answer: Lots of them....especially smash hits.)
What they are doing is sonically expanding to the climax. Why only expand upward? If you are able to go lower while they go higher the song just gets BIGGER. Lots of hits were RECORDED with a 4 banger. And that's great. But when I get to the bar, or the church, and we're trying to whip up a crowd, I will hit the bass version of "the big note" near the end.
Gunpowder and Lead. Last chorus I'm playing the 4 (C) down low while our female singer goes off and our lead guitar player is setting the place on fire.
Last chorus of a Journey song while I'm hanging on for dear life vocally on the Steve Perry big note? I'm going as low as my bass will go and my guitar player is blazing a Neal Schon screaming lead trail right through our audience's brains.
It just gets BIGGER at the end. Forget what "can" be done on a 4. I'm not anti 4 string. But you can take a song, and a show, to a "whole nuther level" by sonically expanding to the end of a song several times a night.... especially at the very end.
Sure you can get away without it. I can get through a Friday night without cheating on my diet with beer and wings too. But why would I WANT to?
