Minor7 and major7
« on: January 29, 2010, 01:08:00 am »
I feel I have a decent understanding of all of the material presented.  I do have one question though.  I am somewhat puzzled on the naming of the chords but have just been accepting them for what they are.  A major 7 chord is 1357.  A dom 7 chord is 135b7.  I understand that.  A minor chord is 1 b3 5.  So it is my understanding that anytime I want to make a chord minor, I simply flatten the 3rd. 

My question comes with the minor 7 chord.  When going through the lesson and trying to work this out for the first time, I would have said the minor 7 is 1 b3 5 7, which I know is incorrect.  It is 1 b3 5 b7.  So based on my knowledge it would make sense to name this minor dom 7 and not minor 7. 

Would it be safe to conclude that when you make a triad minor, you flatten the third and when you want to make a quadrad minor, you flatten the third and seventh?  I was confused by this but have just been accepting it.  If this is explained in the book or on another lesson, I must have missed it.  An explanation would be helpful.

Thanks,
Jon

Dom 7th is usually shortened to just 7, what you have done in the highlighted section is make it a Major7th.
I would name that highlighted chord mM7 (minor, major7th)

Caveats
(1) I was warned that this thread is over 120 days old, but since it's still the top thread in this forum by post date I wanted to reply anyway.
(2) I don't own the Chord Construction Guide but I'll try to help here.

My question comes with the minor 7 chord.  When going through the lesson and trying to work this out for the first time, I would have said the minor 7 is 1 b3 5 7, which I know is incorrect.  It is 1 b3 5 b7.  So based on my knowledge it would make sense to name this minor dom 7 and not minor 7. 

Take a look at any minor triad which occurs when you build on notes of the major scale. If you extend the triad to add the 7th, it will always be a minor 7th. This is true for the Dm Em and Am triads which occur naturally in the C major scale - Dm because Dm7 with the addition of the note C  (a m7 above the chord's root), Em becomes Em7 with the addition of the note D (also a m7 above the chord's root).

As Tourniquet indicated, a chord like DmM7 (notes D F A C#) has a name, but it's not a common chord or one that appears naturally when you build chords on a diatonic scale.

Hope that helps others who might read this, even if it's been a while since Jskeans originally asked.

for min type chords you flatten both the 3 and 7th.

it's kinda odd, but just the way it is.

Tourny and Zapped both right too!
