How to Play Halley's Comet by Billie Eilish on Guitar

Halley's Comet is one of Billie Eilish's most lyrically and musically sophisticated songs. The instrumental break introduces a modulation from G major to Gm/C/F/Dm — a striking key shift that captures the song's emotional complexity.

Capo on the 4th fret allows you to play G-based shapes in the actual key of C#m, while the Cm chord adds the characteristic chromatic tension.

Tips for Playing Halley's Comet

  • Capo 4 — G/Em/C/D shapes sound in B/G#m/E/F# in concert pitch.
  • The B7 chord is the key colour: standard B7 (X21202) — no barre chord needed.
  • The bridge modulation to Gm/C/F/Dm: shift capo or play barre chords for this section.
