The vocal coach Evan Bortnick was 10. January 2014 at Rhine Main guest. Theme was, how students can find their optimum pitch and train. In addition there was a series of practical exercises, the students tried before each group. Depending on the personality (and the appropriate voice) recommended Evan Bortnick different applications: standing to articulate times on a thick rope sounds and words, times to speak to a elevator pitch only with the vowel "u" instead of each vowel.
The lecture was an exciting way, how to work on one's own voice and how small changes result in amazing effects. The drawings above are an excerpt from the entstandenem to the lecture Sketchnote.
