Another simple two-part invention this time, although there's a slight wrinkle. Instead of being in E minor, it's actually in E Aeolian mode. The tip-off is the lack of D-sharps that would give the piece a B major chord to act as the dominant.
How this invention unfolds is up to you, although this may be one I finish myself. All I ask is that if you decide to use this material, just share the results.
