  1. Hi Alex,
    Re: Blue Monk – what does subV mean?
    Thanks, Diana


    1. Hi Diana Roy! subV is for substitution of the V, you may have heard it under the term “tritone substitution”. In a nutshell, the characteristic of a dominant chord is the interval of a tritone between the third and the seventh (on G7 the interval between B and F is an augmented fourth = 3 tones = 1 tritone).
      We realized that another dominant chord has the same interval with enharmonies (enharmonie is the fact that we can have the same sound but different names: the sound of the note B = Cb = A double sharp).
      The other dominant chord is Db7 which has a tritone between F and Cb (that is a diminished fifth = 3 tones = tritone). Db is also a tritone away from G.
      This is a very commonly used device to add momentum. On D-7 | G7 | C∆ we very often play D-7 | Db7#11 | C∆ or if you have two bars of a dominant chord you can add the subV, for instance on the bridge of a rhythm changes:
      E7 | E7 | A7 | A7 | D7 | D7 | G7 | G7 | becomes E7 | Bb7 | A7 | Eb7 | D7 | Ab7 | G7 | Db7 |
      The subV are always with a #11

      Just type some keywords and it will bring you right to the moment in the video where I say these words.


      1. Thanks Alex!
