Minor add2 and add9 chords
The minor add2 and add9 chords are similar to the add2 chord and add9 chord; but adds a note to minor chord instead to a major chord. A common minor chord includes the first, the minor third and the fifth notes in its scale. By adding the second or ninth note, you get an madd2 or madd9 chord respectively.
So if C minor is used as an example, what happen is that C, Eb and G changes to C, D, Eb and G (Cmadd2), or to C, Eb, G and D (Cmadd9). The notes are the same, only the order differ, and because of that you could play madd2 when madd9 is mentioned and vice versa.
The Cmadd2 version presented is more correctly named Cmadd2/D. It's difficult to find proper shapes for this chord, but you can see an alternative below. An easier way to play Dmadd2 is as X03230, in which case the correct chord name is Dmadd2/A.
The minor add2 is close related to the minor add9 and are in a sense equivalent. Yet, if you are meticulous with the sound, you probably want the added tone closer to the root note when choosing minor add2 instead for minor add9.
Another possible abbreviation for these chords are Cmin add2, Dmin add2 and so on.
