Fr. Weber's Proper of the Mass usually has verses set to Psalm tones, but it looks like for the 27th, 28th, and 29th Sundays in Ordinary Time (maybe other times, but not that I found flipping through) the Offertory verses are set much more elaborately and differently for each verse (see attached for an example). I assume they're based on the more neumatic verses that exist for the Offertories (EDIT, they appear to be: https://gregobase.selapa.net/chant.php?id=18135). Does anyone know if there are more somewhere? Our cantor added one to Bruce Ford's Offertory today and it was much nicer than Psalm tones.
