Musical performance
This kind of performing arts is a lot tiring than that of plain acting. Vocal practice joined with acting class is crucial. Good thing San Diego Acting Schools offer classes with musical and voice lessons. Where you can practice acting then there are also parts of the course where the students practice their breathing skills after the voice lessons. Theater is where musical performance is usually watched but nowadays it is being used in commercials and movies. So go for the acting schools in San Diego and if you have skills and are interested on musical acting go for that kind of workshops.
