Da Capo

Da Capo (Ital. from the beginning), in Music, is printed at the end of the second part of an air with two parts, to signify that the first part must be repeated as a conclusion. Another form of it is Dal Segno (from the sign).

“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.”
Matthew 28:19
