Sing-along

For example, a lion pride and a pack of wolves are known to vocalize together (supposedly to defend their territory), although some scholars do not characterize their vocalizations as "singing".

Various species of birds also sing in duets and choruses, particularly in the tropics.

Singing in groups is one of the universal features of human musical cultures, and group singing has been often suggested as the primary form of the early human musical activity.

Informal group singing can be accompanied by body movements, stomping, or clapping.

Sometimes individual musicians will share their own songs with the group, but more often an individual will request a song that the whole group will sing together.
