Discuss some specific ways that formulas are used in Vernacular music. In other words, how do musicians use formulas in the process of "playing by ear?"

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.

Idon’t believe there is a option for that best of luck though
