I do custom 4-part vocal arranging once in a while. Contact me (1-615-371-1700), letting me know about your project. If it sounds like fun, and i have the time, I may do it. You are responsible to submit to Sweet Adelines International (SAI) or the Barbershop Harmony Society (BHS) an application for "permission to arrange." The cost is $50. For choruses, please have your chorus Director or Director's Assistant contact me personally. For quartets, any member can give me a call.
