It’s Music Monday! This year marks the 100th anniversary of the MFA’s musical instruments collection—one of the oldest in the U.S. This Welsh bowed lyre, called a crwth, was among the first instruments acquired by the Museum. With origins dating as far back as the 11th century, several of the crwth’s strings are played all at once by the bow, producing wonderful chordal effects.
