A worked project brief: the source, creative direction and listening checks below show how to prepare this task.
Starting material
An existing song with a verse ending at 0:32. Select that point to continue toward a chorus.
Creative direction / prompt
Continue from this point into a more open chorus. Keep the established groove and vocal character, bring in wider guitar chords and a light tambourine, then let the final phrase resolve gently.
What to listen for
Listen across the join for a consistent pulse, compatible harmony and a natural lift into the next section.
