Which is correct:
[color=blue]1-The singing of the choir of “The Hymn to Beauty” moved us all.
2-The singing by the choir of “The Hymn to Beauty” moved us all.
3-The singing of “The Hymn to Beauty” of the choir moved us all.
4-The singing of “The Hymn to Beauty” by the choir moved us all.

The choir singing The Hymn to Beauty moved us all.
