The melody of I Wish It Would Rain by The Temptations runs 178 notes across 21 bars, 1:44 long in Eb at 80 beats per minute. The tab sits low on the neck, mostly under the fourth fret, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
