I am a violinist. I have several different groups.
1) duo, violin and guitar, we play classical, jazz, flamenco and world music.
2) duo, with piano and violin: jazz, classical, Broadway, and pop.
3) Trio, with piano and bass, Jazz
4) Quartet, string: 2 violins, viola, and cello: Classical
5) Quartet, string: 2 violins, viola and cello: Pop with a percussionist: our booker : Boris Goldmund; Stringalicious
My duo and trio are me with a male pianist and male bass player, upright bass and/or electric bass.
We can add drums, for a quartet.
The string quartet is four girls, classical.
There is also a pop string quartet, all girls, with matching outfits and incredible arrangements, from Beatles to Michael Jackson to Lady Gaga, Pink, Britney Spears, and musical theater: i.e. West Side Story, Fiddler on the Roof, etc., with a percussionist to add to the background and 'pop it up'. For that particular ensemble, named Stringalicious, we work through our booker, Boris Goldmund.
