Bb Minor Triads

Playing triads is a great way of exploring the minor chord and the guitar fretboard more generally. By arranging the notes of the chord systematically using permutations (root position, first inversion, second inversion), interesting and unique shapes and voicings are created. The three different voicings for the B flat minor triad are:

  • Bb minor Triad (Root Position) – Bb, Db, F
  • Bb minor Triad (1st Inversion) – Db, F, Bb
  • Bb minor Triad (2nd Inversion) – F, Bb, Db

By playing these triads on two different groups of three strings, we can produce six different shapes.
