How to use these chords

  • I, IV and V (B, E, F♯) are the primary chords. Together they contain all seven notes of the scale.
  • vi (G♯m) and iii (D♯m) each share two notes with I, and ii (C♯m) shares two notes with IV, so these minor chords often stand in for them.
  • V7 (F♯7) contains the leading tone, A♯, which pulls up to the root, so it resolves strongly to I. vii° (A♯dim) has the same upper three notes as V7 and is mostly used as a passing chord.
  • Common progressions, in Roman numerals: I V vi IV (B, F♯, G♯m, E); I vi IV V (B, G♯m, E, F♯); ii V I (C♯m, F♯, B); ii7 V7 Imaj7 (C♯m7, F♯7, Bmaj7).

Common uses of B major

  • On a piano, 5 of its seven notes are black keys.
  • The root note, B, is an open string on a guitar in standard tuning (E A D G B E), so it can ring under the chords.
  • In the Camelot system DJs use for harmonic mixing, B major is 1B; tracks in 12B, 2B and 1A usually mix smoothly with it.
