The melody of High Hopes by Panic! At The Disco runs 521 notes across 96 bars, 2:46 long in Bb at 163 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? High Hopes chords and lyrics.
