Elmer Ellsworth McMeen, III (known as El McMeen), born June 3, 1947 in Lewistown, Pennsylvania, is an acoustic steel-string fingerstyle guitarist. His specialty is fingerstyle arrangements of sung or strongly melodic pieces, ranging from the Irish genre, to hymns, gospel tunes and pop music. He has also composed instrumentals for guitar, and has published a book of Irish and Scottish instrumental music that he arranged for classical string trio (violin, viola and cello). That book is called Celtic Treasures for String Trio (Piney Ridge, 2005). He plays and arranges guitar music almost exclusively in the CGDGAD tuning. (That tuning, developed by English guitarist Dave Evans in the 1960s, is similar to a Hawaiian slack-key tuning [CGCGAD] called "C Ni'ihau" tuning.) Acoustic Guitar magazine (Oct. 2001, No. 106) called McMeen "the king of CGDGAD tuning".
