MUSIC

Music is an important part of our life as it is a way of expressing our feelings as well as emotions. Some people consider music as a way to escape from the pain of life. It gives you relief and allows you to reduce the stress. Music plays a more important role in our life than just being a source of entertainment.
Vocal music is a genre of music performed by one or more singers, with or without instrumental accompaniment, in which singing provides the main focus of the piece. Music which employs singing but does not feature it prominently is generally considered instrumental music as is music without singing.
Instrumental music involves just instruments — no singing. If you like instrumental music, you dislike vocals. An instrumental song is one without a singer, and there can be instrumental passages of any song, where the band just plays and the singer is quiet. But this word also means something like useful.
