which means any song with that same meter will work, though I’ve suggested a few that use C.M. Well, actually it was there mostly for the amusement of musicians since most churches never did switch up tunes or lyrics. If you grew up with hymnbooks, you know there was a metrical index in the back and it’s there for a reason. My Hope is Built is based on a rhythmic structure called Long Meter or simply L.M. This song incorporates the lyrics of the old hymn, My Hope is Built, and then adds a chorus, “Cornerstone, Christ alone weak made strong in the Savior’s love…” If your church does modern worship, odds are that in the last few months you’ve been doing the song Cornerstone by Hillsong.
