minor major seventh chords by: Ido from www.piano-play-it.com
Hi Daisy,
The chord is a B minor, major seventh.
It has various symbols:
mM7, mΔ7, -Δ7, mM7, m/M7, m(M7), minmaj7.
All of these symbols mean exactly the same: a minor chord with an extra note which is placed a major seventh above the bass.
I'd like to explain the logic behind this for you
The first three notes of the chord - B, D , F# construct a B minor chord. The question is - what does the Bb do there?
First of all, I advise you to go to our piano chord section which explains everything you need to know about chords and their structure.
Regarding the added note-the Bb: Well, actually it is more correct to refer to it as an A# instead of a Bb. (These are the same notes with different names). Therefore, the notes of the chord are: B D F# and A#. This is a seventh chord because it is constructed of 4 notes which are positioned in thirds from each other.

Let's examine the Bm7 chord (I assume that you know what is its structure; if not, click here). It consists of these notes: Bm7 = B D F# A.
The A is the seventh of the Bm7 chord, so in your case the A# is the major seventh of the same chord. This is why we call this chord - B D F# A.# - a minor, major seventh chord.
