Dominant seventh suspended second chord

A dominant seventh suspended second chord is composed using a root/1^st, major 2^nd, perfect 5^th and minor 7^th (or R/1-2-5-♭7) intervals played simultaneously. Generally written as C^7sus2 or C^7(sus2), it is good practice to simply use an uppercase C followed by a super scripted ^7sus2 to represent it in writing (ie: C^7sus2).

The dominant seventh suspended second chord is enharmonic to a minor seventh suspended second chord as there is no 3^rd degree present in either, and both have a minor 7^th interval. Like the suspended second chord, its quality (ie: minor or dominant) is implied by its resolution (if any) however in this instance, resolution is either minor or dominant, not major (this is due to the minor 7^th being present in both). As an example, if you were to play a D^7sus2 followed by a D⁷, the implied quality would be dominant because the major 2^nd (suspended 2^nd) is resolving to a major 3^rd one whole step higher, while the minor 7^th remains. Alternatively, if you were to play the same D^7sus2 chord but this time follow it with a Dmi⁷, its implied quality would be minor because the major 2^nd is resolving to a minor 3^rd one half step higher, once again the minor 7^th remains.

It is not necessary to resolve the dominant seventh suspended second or the minor seventh suspended second chords, it is merely a tonal tool we can use if required.
