We again focus on 7th chords, and specifically on the C aug 7th mandolin chord. Although there are many positions (ways, variants etc.) to play the C aug7 mandolin chord, I suggest you start with the slideshow that shows the most common mandolin chord positions for C aug7 – displayed on the top of the page above, fingered for your convenience.

What is a C augmented 7th (C aug7) chord?
The C aug7 is a 7th chord, i.e. it consists of C-Eb-Gb i.e. a diminished triad and C-Bbb i.e. a diminished 7th interval. When these two are combined, they create Caug7 as following
The root, which for the C aug7 chord is of course C
The third, which for the C aug7 chord is E. Note that this creates a major third interval that consists of four half steps (C to C#, C# to D, D to Eb, Eb to E)
The fifth, which for the C aug7 chord is G#. Note again that this creates a major third interval that consists of four half steps (E to F, F to F#, F# to G, G to G#).
The seventh, which for the C aug7 chord is Bb. Note that this creates a diminished third interval that consists of two half steps (G# to A, A to Bb).
The C aug7 is an augmented 7th chord, because the interval between the root (note C) and the fifth (note G#) is a augmented fifth interval.
Note that half steps correspond to one fret difference between notes played on the same string.
