Announcing Classical stations employ program hosts, not DJ's These hosts are expected to know and appreciate the music. Pronunciation is critically important. Classical hosts are allowed to have personalities. Often the audience tunes in because they like the host and the host's interpretation of the music as much as they like the music. News News is still important at classical music stations.
Some stations concentrate on updates as opposed to full newscasts.
However, the audience is perceived as educated and informed. Drive times are the most common news times. Features Classical music stations depend heavily on features. Features are primarily live concerts or recorded concerts of specific orchestras. For example the Chicago Symphony Orchestra, The New York Philharmonic, or the Boston Pops.
