Minor 7th Chords are represented as m7 or -7, with m7 being the most popular... the 7th note is a minor 7th above the root note or tonic.
- The chord is in essence a minor/minor chord, as it is a minor chord with a minor 7th. This in in contrast to a minor/major 7th chord where you have a minor chord with a major 7th.
- A minor 7th chord is a chord having a root, a minor third, a perfect fifth, and a minor 7th.
- The chord formula for a minor 7th chord is 1 - ♭3 - 5 - ♭7
- We calculate the notes of a chord from the Major Scale of that particular chord, e.g., the notes of a Gm7 chord are derived from the G Major Scale, the notes of a Cm7 chord are derived from the C Major Scale etc. In the following example, we will calculate the notes of a Bm7 chord...
|Chord Name + (other less-common names)
||Bm7 ( B min7, B-7)
|B Major Scale (B chords are derived from the B Major Scale)
||B - C# - D# - E - F# - G# - A# - B
|Chord Formula for all m7 chords
||1 - ♭3 - 5 - ♭7
|Chord Notes (after applying the formula to the Scale)
||B - D - F# - A
