One of the reason why people listen to music is to relax their mind and body. People in the music business hear hype all of the time, and for the most part are numb to it. Hype is good to use with the general public on things like posters (they often believe it), but your press kit reader is more sophisticated and will see it as cheap theatrics.
This development is significant particularly because cassettes, which are inexpensive and portable, gave control over production to local artists, or at least to agencies that were closer to the artists than a national radio company or a European-based recording company.
Classical music encompasses instrumental and vocal music written by trained composers, expressing cultivated artistic and intellectual values, as opposed to music of an essentially commercial nature (popular) or music that develops anonymously and is transmitted aurally (folk).
Early American performers and composers lacked the main sources of patronage that supported the European tradition of art music, such as the aristocracy and the Catholic church, and depended on entrepreneurs willing to market classical music to the public.
Other composers like the cosmopolitan virtuoso Anton Rubinstein or Peter Tchaikovsky, who received his professional training in Russia at the Petersburg conservatory founded in 1862, had fewer reservations about being inspired by the West, though Tchaikovsky, too, wrote genuine Russian music.
