Barbershop vocal harmonies arent very popular
Yeah I've heard them in random pop culture and shows but I haven't seen much elsewhere.
it was a capella style popular in the 1930s
No wonder I don't see much of it, that's a long time ago.
Yea barbershop harmonies and vocal capellas are very uncommon now
They are uncommon but it is honestly kind of nice and interesting to listen to them.
the harmonies used some old style methods of snakes and swipes, typical in barbershop harmony
There is also usually a lot of piano and harmonizing in it.
Occasionally they are sung by fewer than four people
Really? It would be hard to sound like a classic one with less than four people!
