The B chord
Start with the recipe. The notes are B - D# - F#, a major triad, otherwise known as the B. The chord feels bright and stable, which is why writers chasing a stable home keep landing on it. Most guitarists barre it at the second fret; piano players treat it as a comfortable five-sharps shape. You will find it inside campfire songs and stadium choruses. The rest of this page lays out the common voicings, the interval theory, the progressions where the chord fits, and the records that lean on it for structural work.
