A# Piano Chords

All A# piano chords — click any card for full diagrams, inversions, audio, and notation.

A♯ is the black key just below B. Written as a major key it would need double sharps, so its chords and scales are spelled as the enharmonic B♭ in practice; on the keyboard they are one and the same. Every chord type rooted on A# is listed below — triads, sixths, sevenths, and extended and altered voicings — each with diagrams, audio, and notation.
