Keith & Kristyn Getty currently have sheet music for five of their Easter themed songs available as a free download from their website.
The link to the pdf is here.
The sheet music looks like piano scores.
Along with new song Christ is Risen, He is Risen Indeed!, older songs O, to See the Dawn (The Power of the Cross) (twice!); In Christ Alone; My Heart Is Filled With Thankfulness; and Communion Hymn (Behold the Lamb) are included.
I’d think most of these are pretty widely known. Maybe Communion Hymn slightly less so. If you haven’t heard it, it’s worth a listen.
