Hymns around the piano 🎹 - "Hymns are for kids"

A song that is pleasing to the ears of a young learner (of any age) can be that lesson "supplement" that keeps them going. Hymns are written in four singing parts. Locating and adding that harmony note (usually below the top note, typically also played with the right hand) to the melody in the treble clef is rewarding. Once the lowest note from the base clef is added, you'll be fueled to get them all down and press on to get through a measure or two. Of course, there's different ways to get there, but hymns are a great way to build confidence and momentum. Adding to the parts as a pianist, often when they are "held," is somewhat intuitive. Some pianists are gifted to "play by ear" and/or rely on an understanding of chords and the notes in the key signatures.
In Marian Talley's Gospel Piano Profiles (Schaum,1973), she has written in some octaves, rhythm, and arpeggios to help the student -- some of which can be played with little practice. You might find some of the passages musically "dated" ("vintage" came up in the web search), but almost all of the 11 have stood the test of time, speaking to millions spiritually. "Jesus Loves Me," was written by Anna B. Warner as a poem to comfort a child, with William Bradbury adding the tune and chorus in 1862. Edward Caswall translated the majestic German hymn "May Jesus Christ Be Praised (When Morning Gilds the Skies)" with music by Sir Joseph Barnby.
