There are many different types of blues music. Best known the Delta blues, Piedmont blues, Jump blues and Chicago blues styles.
The Delta blues is one of the earliest types of blues music. It originated in the Mississippi Delta. They used guitar, harmonica and cigar box guitarare, with slide guitar (usually on the steel guitar) what became a hallmark of the style. The vocal styles range from introspective and soulful to passionate and fiery.
Piedmont blues (also known as East Coast blues) refers primarily to a guitar style, the Piedmont fingerstyle. The term was coined by blues researcher Peter B. Lowry, who in turn gives co-credit to fellow folklorist Bruce Bastin. The Piedmont style is differentiated from other styles, particularly the Mississippi Delta blues, by its ragtime-based rhythms.
Jump blues is an type of blues usually played by small groups and featuring horns. It was very popular in the 1940s, and the movement was an introduction to the rhythm and blues and rock and roll. More recently, there was renewed interest in jump blues in the 1990s as part of the swing revival.
The Chicago blues is a form of blues music that developed in Chicago, Illinois, by taking the basic acoustic guitar and harmonica-based Delta blues, making the harmonica louder with a microphone and an instrument amplifier, and adding electrically amplified guitar, amplified bass guitar, drums, piano and sometimes saxophone and trumpet. The music developed in the first half of the twentieth century as a result of the Great Migration, when Black workers moved from the South into the industrial cities of the North such as Chicago.
