We now focus on 7th chords, and specifically on the C minor 7th mandolin chord. Although there are many positions (ways, variants etc.) to play the C m7 mandolin chord, I suggest you start with the slideshow that shows the most common mandolin chord positions for C m7 – displayed on the top of the page above, fingered for your convenience.
For practical reasons, I have included also a Chord Chart for C m7 on mandolin, feel free to print it.
What is a C minor 7th (C m7) chord?
The C m7 is a 7th chord, i.e. it consists of four notes as following:
The root, which for the C m7 chord is of course C
The third, which for the C m7 chord is Eb. Note that this creates a minor third interval that consists of three half steps (C to C#, C# to D, D to Eb)
The fifth, which for the C m7 chord is G. Note again that this creates a major third interval that consists of four half steps (Eb to E, E to F, F to F#, F# to G).
The seventh, which for the C m7 chord is Bb. Note that this creates a minor third interval that consists of four half steps (G to G#, G# to A, A to Bb). As C to Bb interval is a minor 7th interval, we call this chord C minor 7th.
The C m7 is an minor 7th chord, because the interval between the root (note C) and the seventh (note Bb) is a minor seventh interval.
Note that half steps correspond to one fret difference between notes played on the same string.
