Pr. Lehmann made me write this one. It's just my notion of what days you HAVE to sing certain hymns on. It's not a complete list, but it is a start, and I'd welcome other thoughts. It's not that these hymns are necessarily the best or the greatest for a given day, but that (at least at St. Paul's, Hamel) these hymns are EXPECTED on a given day, remembering we use the historic or one-year lectionary:
Easter - don't even think about skipping "Jesus Christ is Risen Today, Alleluia" or "I Know that My Redeemer Lives."
Easter II - you have to do "O Sons and Daughters" and use the Vulpius tune - the other one won't fly here.
Easter III - "The King of Love" with the tune from LW.
Ascension - "On Christ's Ascension" is a must.
Pentecost - "Come, Holy Ghost, God and Lord" simply HAS to be the hymn of the day.
Trinity - "Glory be to God the Father" better be in there somewhere.
Trinity I - Who could think of skipping "Lord, Thee I Love"
Last Sunday after Trinity - "Wake, Awake," what else?
Advent I - "Savior of the Nations" reigns supreme
Advent IV - "O Come, O Come, Emmanuel" must NOT be monkeyed with
Christmas Day - if you get in "O Come, All Ye Faithful," "Angels We Have Heard on High" and "Joy to the World" you are playing it safe. If you can convince them that a Christmas without "Of the Father's Love" is unthinkable, blessed are you!
New Year's Eve - you MUST sing "Our God, our Help" and "Across the Sky" - and on the last one LSB really improved the words.
Epiphany - I HATE the hymns for Epiphany, but you have to sing them: "Brightest and Best" and "As With Gladness" - but I put up with them because the Hymn of the Day has to be "O Morning Star" and that more than makes up for sentimental 19th century tunes and text.
Epiphany I - "The Star Proclaims" is a must.
Transfiguration - here is one that I insist on: "O Wondrous Type" - congregation is still in the learning to love it phase. But they WILL love it; it's not really an option. Such a great text wedded to that great Agincourt tune.
Lenten Services - the great chorales "Jesus, I will Ponder Now," "A Lamb Alone" and "Ah, Dearest Jesus" are all musts somewhere along the line.
Palm Sunday - besides the opening "All Glory" you HAVE to get in there "Ride On, Ride On" with the old TLH/LSB tune.
Good Friday - "O Sacred Head" is not optional
And we're about where we started. There are others, but those are the "must sing" hymns that come to my mind for the Church year. Do you have others?
