Triodion Prokeimena Errata
On pp. 45 and 46 (Holy Friday Vespers, and Holy Saturday Matins), the Alleluias in the 5th Tone, in the bass part, the F on the “le” of the third alleluia should be an A, two steps up.
On p. 16 (Thursday of the 2nd week, 6th Hour), the first prokeimenon is missing the phrase “…from my tribulations.” The music will have to be re-written. When I do so, I will add it into this post as an image file.
