At this point, we have looked at the theme and three variations. Now try to apply these principles and create a few bass variations of your own. Follow these guidelines:
- Use a standard harmonic structure (I will suggest a few below).
- First write a “theme” using repeated notes only. Try to use a dotted rhythmic pattern to add energy to this theme.
- Use repeated notes, octave displacement, and goal orientation in your other three variations.
- Improvise these at the keyboard until you find patterns you like (this is a single bass line, so it should be feasible even for non-pianists)
- When you are happy with your diminutions, write them down.
Here are few suggested bass lines:
