In this paper, Wilson elaborates more on the notation he first brought up in 1974. First, he brings up three families of fifths and their direction on the Bosanquet keyboard: | In this paper, Wilson elaborates more on the notation he first brought up in 1974.

Although the positive & negative notations of each family are part of the same system, they require different treatments in order to stay melodically consistent. Thus, there are different nominal systems for each kind of system. He gives four examples: | Although the positive & negative notations of each family are part of the same system, they require different treatments in order to stay melodically consistent.
