Effective messaging

When determining the message content we also have to think what flavour, personality or association will be needed to have the desired effect on the audience. Musicians do this all the time. As this is Eastern, here are - thanks to YouTube - seven examples of the "Erbarme Dich" Aria from Bach's St Matthew Passion. And these are the 'flavours' I hear/see:
1. The awe for the distant divine (Eula Beal, Yehudi Menuhin, Antal Dorati, US late forties).
2. A subdued desperation about loss and mercy (Herbert von Karajan, Kathleen Ferrier, UK, late fifties).
3. A personal appeal for transparency, harmony and compassion (Julia Hamari, Karl Richter, Munich Bach Orchestre, late sixties).
4. The power and volume of musical performance and perfection over guilt and pity (Vladimir Spivakov and Tamara Sinyavskaya, Russia, late nineties) .
5. The quality of sound to evoke universal sympathy (Makiko Narumi, Japan, 2000)
6. Reading heartfelt sorrow from the score (Maureen Forrester, Antonio Janigro, I Musici di Zagreb, 1997).
7. The mystique of how it must have sounded in Bach’s time (Delphine Galou, Francois-Xavier Roth and Orchestre Les Siecles, France, 2009).
