This Hub is the first in a series dealing with the part-writing issues—the ‘tricks and traps’—involved in using seventh chords. But the series is the third of three sets (so far) on part-writing! So it’s not too surprising that the present Hub assumes a fair amount of knowledge: proficiency in reading music in treble and bass clefs, knowledge of the basic rules of part-writing, and skill in using at least tonic and dominant triads in root position and inversion.
It may help in assessing this question to have a look at the summaries of the Series I & II Hubs. Those summaries can be accessed by clicking the links in the sidebar at the right.
