About C#sus2
C#sus2 is built from three notes: C# (root), D# (second) and G# (perfect fifth). In scale degrees above the root, the formula is 1 – 2 – 5. With no third it leaves the harmony undefined: it sounds open and modern, and it is used a lot in pop and rock.
C#sus2 has no standard open shape in the CAGED system, so its 27 voicings are sorted only by difficulty and position on the neck. Another way to write C#sus2 is Dbsus2 (the same piano key, with a different name). The usual choice is Dbsus2.
