My three that are set up in the family room would sing a pretty song. Miss Elna takes care of all household sewing, the 301, AnnieRose, is the FMQ queen. The 15 clone with shamrocks stitches very straight so she's good at piecing. So they would sing a nice harmonious song. Right now AnnieRose is piecing because she's quieter. Maybe she's saying Nah, nah, nah, nah to the pretty black machine.
