I think that one of the biggest attractions to me was the deeper sound of the baritone ukulele. I had been regularly playing my GCEA tuned concert ukulele with a low G for a couple of years so I have had been thinking about how I can get more of that bass sound out of my bari. These videos about Brushy and his music are inspirational.
Brushy has his guitar set-up with only one string and has a really exceptional sound. Truly musical people can make any instrument sound great. I wonder how this type of sound could be incorporated into a bari player's repertoire. I don't know how a bass player thinks, I mean what is the musical theory behind bass playing, but this seems like something that would be interesting to try out.
My multi-instrumentalist buddy Rhan Wilson also plays bass, perhaps I can get some insights from him. I have been fiddlin' about with making some Diddley Bo's and they are one-string instruments. I have a few pictures of a two-string Diddley Bo that I made for my son here.
Here's his story about how he got started. You'll have to listen carefully...
