Have you ever thought why Russian musicians are so good?
Here is the answer:
Russian musicians study solfeggio (sight singing + ear training + musicianship etc.) from the early childhood weekly.
American early music education system works differently. American young students don't really have this class.
As a result only by the time music students go to college, they realize the lack of this training. But it's too late. Solfeggio will never be their native language. It means that they will not be able to compose music, to play by ear etc.
Now you have this opportunity.
Olga Vasiliev was a solfeggio teacher in Russia (Moscow, Saint-Petersburg). She continues teaching solfeggio in De Anza College, Cupertino and she is teaching solfeggio in her school. Do not lose this chance!
