The music of Baltimore, the largest city in Maryland, can be documented as far back as 1784, and the city has become a regional center for Western classical music and jazz.
 Early Baltimore was home to popular opera and musical theatre, and an important part of the music of Maryland, while the city also hosted several major music publishing firms until well into the 19th century, when Baltimore also saw the rise of native musical instrument manufacturing, specifically pianos and woodwind instruments. African American music existed in Baltimore during the colonial era, and the city was home to vibrant black musical life by the 1860s.
 Baltimore's African American heritage to the start of the 20th century included ragtime and gospel music.
 By the end of that century, Baltimore jazz had become a well-recognized scene among jazz fans, and produced a number of local performers to gain national reputations.
 The city was a major stop on the African American East Coast touring circuit, and it remains a popular regional draw for live performances.
 Baltimore has produced a wide range of modern rock, punk and metal bands and several indie labels catering to a variety of audiences.
