Musical Theatre (26) - Investigation into Musical Theatre

To prove that we understand Musical Theatre we have been asked to show evidence of a "detailed investigation into the key features of musical theatre performance". Having done my "Special Subject Investigation" unit on Musical Theatre, I have already done a lot of research into this topic! (The following is a link to my "Special Subject Investigation" unit blogs - http://lornaclarkra.blogspot.co.uk/search/label/SSI ). 

The BBC Bitesize Website has a lot of information on songs, stating the difference between action songs (which move the narrative along) or character songs ("which enable characters to express their feelings"). The song types are as follows: ballads (reflective/romantic), comedy, production numbers (ensemble songs) and rhythm songs (energetic rhythm patterns).
