The major triad is the most fundamental chord in Western music, built from the root, major third, and perfect fifth. It has a bright, stable, and resolved sound. The B Major Triad specifically contains 3 notes: B, D♯, F♯ (formula: 1-3-5). On guitar, B-rooted chords are typically played as barre chords at the second or seventh fret, and on piano they use a comfortable mix of black and white keys.
