There are many positions (ways, variants etc.) to play the D augmented mandolin chord. In this article you can find the most common mandolin chord positions – displayed on the slideshow above, fingered for your convenience.
To help you understand how to play them, I have included explaining how this chord is created and what notes it contains. Finally, the article includes a chord chart with all possible mandolin chord positions for future reference, feel free to print it.
What is a D augmented (Daug) chord?
The Daug is a triad chord, i.e. it consists of three notes as following:
The root, which for the Daug chord is of course D
The third, which for the Daug chord is F#. Note that this creates a major third interval that consists of four half steps (D to D#, D# to E, E to F, F to F#)
The fifth, which for the Daug chord is A#. Note again that this creates another major third interval that consists of four half steps (F# to G, G to G#, G# to GA, A to A#).
The Daug is a augmented chord, because the interval between the root (note D) and the fifth (note A#) is an augmented fifth interval.
Note that half steps correspond to one fret difference between notes played on the same string.
