‘Unresolved…’ utilises a repeating 3 chord pattern. 
The opening chord is a G power chord with no 3rd, hence there is no commitment to either Major nor Minor. The EbM7 has no 5th and the C9 has no 3rd or 7th again not aligning to the Major or Minor.
Numerous titles were suggested by members of the Mark Matthews Piano Compositions Facebook group and "unresolved..." offered by Charlene Valdo of Calgary, Alberta, CANADA was selected.  
it is a single page score for Grade 3 AMEB level difficulty, offering the teacher and student alike a chance to explore the chord structure and improvisational opportunities that may arrise therein.
