Extended information:

Form of expression: Blues is undoubtedly an important part of R&B, but jazz elements are equally important.

The earliest R&B artists came from the fields of "Big-Band" and "Swing-Jazz". Before World War II, when jazz was far more popular than it is today, it was music played for dancing, but there was usually a singer in the band.

During the "World War II", many important jazz artists began to develop "Be Bop" and "Cool Jazz", a type of jazz with fewer dance elements. However, due to the influence and constraints of economic, military and other factors during the war, the number of "big bands" began to gradually decrease.

But listeners, especially those in the rapidly growing African-American communities in big cities, still wanted to hear danceable music. So in order to adapt to the audience, musicians made "Boogie" music that was louder, used more electroacoustic instruments, and focused on "riff".

The R&B style that first became popular is usually referred to as "Jump Blues". It not only absorbs the swing rhythm and horn-based arrangement in jazz, but also absorbs the reply sections and harmonic structures commonly used in blues.

Perhaps the most important pioneer of this style is Cab Calloway. On "Jump Blues," the singer's voice is harsher, the tempo is faster, and the instruments are played differently—the piano is played harder and the saxophone sound is longer and sharper.
