Beschrijving
As spectral instruments appear playing around you, you begin singing a well-known song and others feel compelled to join in. For the duration, when a creature comes within 30 feet of you or begins a turn there, it must make a Wisdom saving throw or begin singing along with you. A singing creature matches the pitch and words of the song as closely as it can, even if it can't speak the song's language. Furthermore, it can't speak normally (though it can still communicate telepathically) and it can't perform the verbal components of spells. Creatures that can't be charmed are immune to this spell.
Unlike other spells, you can concentrate on this spell and the spell Otto's irresistible dance at the same time. Losing your concentration on either spell ends both spells.
