A couple weeks ago, the ICA published a 2-part blog series on the music of Hildegard von Bingen, with several songs transcribed into chant notation:

Attached is the latest: Spiritus Sanctus vivificans, an antiphon for the Holy Spirit. This and other chants will continue to be uploaded to the first blog article as they are completed.
