The term "808" refers to the Roland TR-808 Rhythm Composer, a drum machine that became hugely influential in music production, particularly in hip-hop, electronic, and dance music. It is known for its deep bass kicks and snappy snares, and has been credited with shaping the sound of modern music. The number "808" is often used to describe the distinctive bass sound produced by this machine in songs.
The name "808" originates from the model number of the Roland TR-808, which was released in 1980 by Roland Corporation. The device was one of the first to use analog synthesis to create drum sounds, deviating from traditional samples found in other drum machines.
