The seconds are all discords, and, like all other dissonant combinations, require in general to be prepared, as well as resolved.
Preparation occurs when we previously take a concord suitable to the purpose.
To the minor second there is required, to make it a chord in four parts, the perfect fourth and the minor sixth. Ex.
