The melody of It’s Not Unusual by Tom Jones runs 195 notes across 38 bars, 1:40 long in C at 184 beats per minute. The tab sits almost entirely in the first two frets, 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.
