The Washington Conservatory New Horizons Band camp is for adults who played band instruments in school but haven't played for many years, and for those who have played off and on, and those who played all along. The week will include time to rehearse as a group and in sectionals, get lots of playing tips from the leader, discuss the music, talk about instruments, with plenty of time to socialize and have a good time. Participants are welcome to stay later to read duets or practice your part with others. Anyone who has played for a minimum of one year at any time in your life is welcome! (Bring your own brown-bag lunch or order from nearby options.) More info: 301.320.2770; washingtonconservatory.org. 5 sessions.
