Lyrics

There is (Ab)com ing a day when no heart aches shall come, no more (Eb7)clouds in the sky, (Fm)no (Eb7)more (Ab)tears to dim the eye.

(Ab7)What a (Db)day that will be, when my (Ab)Je sus I shall see, and I (Eb7)look up on His face, the (Fm)One (Eb7)who (Ab)saved me by His grace.

(Ab7)When He (Db)takes me by the hand and leads me (Ab)through the Prom ised Land, what a (Eb7)day, glo ri ous (Ab)day (Eb7)that will (Ab)be!

There’ll be (Ab)no sor row there, no more bur dens to bear, no more (Eb7)sick ness, no pain, (Fm)no (Eb7)more (Ab)part ing o ver there.

(Ab7)And for (Db)ev er I will be with the (Ab)One who died for me.

Easy piano arrangement in the key of Db at 135 BPM. Difficulty: medium. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a wonderful workout for left-hand independence — that oompah bass pattern needs to stay relaxed and steady at 135 BPM while your right hand floats the melody on top.

Start hands-separate and slower, maybe around 100 BPM, locking in the left hand's bass-note-then-chord rhythm until it feels automatic.

Playing in Db means your fingers sit naturally along the black keys, which is actually comfortable once you trust the hand shape.

Watch the move into Bbm7 and Eb7 — those transitions can trip you up if you're not anticipating the chord change a beat early.

The Ab7 resolving back to Db should feel like a satisfying exhale; lean into that.

If any section stumbles, loop just those four bars until they're boring.

This is the piece that'll make oompah patterns in flat keys feel like second nature, and the peaceful mood rewards a light, unhurried touch throughout.
