I wanted to add a brief postscript to Tunde Olatunji's comments on form and content.
Harold Rosen breaks down storytelling into three areas, which roughly correspond to Tunde's form and content analysis. These are:
Story - this refers to the actual sequence of events and experiences that make up the narrative. In other words, this would, I presume, refer pretty much to what Tunde calls 'content'
Harold then divides form into two further categories:
Narrative discourse - this refers to the structure into which the 'story' is placed to create the narrative, such as narrative structure, sequencing, narrative formulae, repetitions, phrasing, etc.
Narrating - this is, of course, the actual process of one person telling the story to another. It involves both teller and listener shaping the narrative and does, I suppose relate to what we generally talk of as performance.
All of the above three categories (but especially the third) are determined by the context in which the storytelling is taking place and it is the trialogue between the three categories (as opposed to a simple dialogue between form and content) which determines the unique characteristics of each individual telling.
I always find Harold's analysis a useful way to think about storytelling and I hope this is a useful addition to the current discussions.
