Hey! Flerb here. On this page, you can listen to and purchase learning tracks that my Robo-Quartet has already made. Due to copyright concerns, you're responsible for finding your own sheet music, but this serves as a pretty good example of what my mechanical minions can do. 

 

Most of these are voiced for men, but my robots are versatile, and can sing in the female range as well. So whether you're a Barbershopper or a Sweet Adeline, my Robo Quartet is ready to serve! Order your own set of Custom Learning Tracks today!
