For those who are new to Irish traditional music, Drew Vervan's "Celtic Music Club" sessions are a great way to get started.  They are open to all who have an interest in playing Irish and Scottish dance tunes.  They occur every Tuesday evening from 6:30-9:30pm at the Catonsville Clubhouse, a community arts center at 10 St. Timothy Lane in Catonsville, MD.  The first hour is a slow session focused on learning basic tunes from sheet music; the rest of the time is a faster session that involves playing more tunes and sets at speed, also from sheet music.  The sheet music is all available online.
