About I performed professionally for over 10 years as part of a trio of a cappella-singing sisters, who also played light classical and celtic instrumental pieces on the harp, cello, violin, recorders, and bagpipes. We performed at many weddings, dinner parties, and shows, and were able to set moods ranging from comedic to reverent. So I have a lot of professional experience in figuring out what you need to do, to get pieces performable, and enjoyable for audiences, fast.
My particular strength is showing beginning and intermediate musicians how to arrange the music they want to play, so that they can play it -now-, with their current instruments and at their current skill level. I feel that music is about communication, and that you don't have to wait until you are an "expert" to be able to make others happy with music.
