These exercises are on a backing track with a gentle jazz-rock feel.

The first part is in C Minor (Dorian) and the second part is in Eb Minor (Dorian).

This type of feel naturally leads to somewhat different kind of phrasing and licks.

Licks are phrases that are kind of generic, and can be used in many musical contexts, they kind of stand on their own. Most phrases in a jazz solo tend to be part of a development, part of a whole, and not necessarily strong in isolation. But if they are, they can be used as licks.
