- A concert is a musical performance of one or more musicians, singers or instrumentalists, in public, free or not, in a place set up for this occasion - a hall, a garden, a church, a square, etc...

- The main purpose of a concert is for the audience to hear the music, but it can also be recorded for later commercialization in the form of a sound or visual recording.

- For example, if a choir interprets a Negro spiritual in public, in a church, it can be a real concert; but if this same choir, in this same church, interprets the same works within the framework of a religious ceremony, it is no longer a question of a concert, but of an element of the liturgy.
