instrumental music:

An instrumental is a recording normally without any vocals, although it might include some inarticulate vocals, such as shouted backup vocals in a big band setting. Through semantic widening, a broader sense of the word song may refer to instrumentals.These interludes are a form of break in the song.

vocal music:

Vocal music is music that uses and emphasizes the human voice. Sometimes instruments are used, but the voice is the most important part. Vocal music is the opposite of instrumental music, which uses any combination of instruments, such as strings, woodwinds, brass, or percussion, usually without the human voice.
