The B♯ power chord (B sharp fifth) consists of the root note B♯ and its perfect fifth F𝄪 (double-sharp), creating the stripped-down two-note structure characteristic of all power chords. While B♯5 is enharmonically equivalent to C5 and appears primarily in theoretical contexts, it follows the same power chord principles—omitting the third interval to produce a neutral, powerful sound. This harmonically ambiguous voicing works equally well over major or minor progressions, embodying the versatility that makes power chords fundamental to rock, metal, and punk guitar. Like all fifth chords, B♯5 excels in distorted guitar settings where its simple interval structure maintains clarity and delivers the aggressive tone essential to heavy music. The rarest power chord spelling in practical guitar music, appearing almost exclusively in theoretical discussions or pieces in C♯ major or F𝄪 (F double-sharp) minor—keys virtually never used in contemporary rock. Functionally identical to C5, the B♯5 notation exists to maintain correct harmonic spelling in extreme sharp key signatures. While a C5 chord appears in countless rock songs (AC/DC's "Back in Black," The Who's "Baba O'Reilly"), calling it B♯5 only makes sense when analyzing its function as the tonic in a C♯ major progression, demonstrating the distinction between enharmonic equivalence (same sound) and functional harmony (different theoretical purpose).
