Thank you I was wondering if for the MAJ 7, there would not have been a "trick" easier (?) I have difficulty between the 5th and 2nd finger to put this space, I will have to practice, for the m7 on the other hand, it is easier, I just checked! I've just checked it, especially since by doing only the bass G plus the Bb chord, the Gm chord is done by itself! In any case thank you...
