Bach's Two Part Inventions

I am familiar with many of J.S. Bach's Two Part Inventions, as well as his Three Part Inventions (known as Sinfonias) and his Preludes and Fugues for keyboard. Although I am well acquainted with the themes of a lot of these pieces, I wanted to have a brief look at what Bach does with the initial idea presented. For this I used my copy of his Two Part Inventions; although the Sinfonias would have more closely resembled the three part texture I will be composing for the assignment, looking at just two parts will enable me to more clearly see the relationship between the two voices, the concepts of which I can then apply to three voices. I noticed the following basic and recurring elements in Bach's Two Part Inventions:

• States theme, imitates at same pitch in other voice
• Restates theme in the dominant, imitates at the same pitch in different voice
• Limited number of different rhythms
• Sections where both voices are busy (semiquavers), but usually one less busy than the other
• Voices often in apart by 3rds and 6th's
• Use of all types of motion - contrary, similar, oblique
• Both voices state melodic ideas
• Use of long / multiple rests in one voice, especially at the beginning when the theme is being stated
• Contrasting articulation
• Constant movement from beginning to end

Without getting bogged down with in-depth analysis of Bach's work, I think I can use some or all of the elements above in my composition for assignment three, which will help to create unity, interest, and clean, independent melodic lines.
