The melody of Telephone by Lady Gaga featuring Beyonce runs 770 notes across 100 bars, 3:40 long in Db at 122 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.
Prefer to strum and sing it instead? Telephone chords and lyrics.
