The minor add4 chord (m(add4)) enriches the minor triad with a perfect fourth, creating harmonic ambiguity between minor character and modal suspension.

Theory
The m(add4) chord combines minor third and perfect fourth. D m(add4) = D-F-G-A, E m(add4) = E-G-A-B. The interval of 2 semitones between minor third and fourth creates a softer sound than in major add4. This chord is used for expressive modal passages.
