TEXT D Naturally the audiences
that support various kinds of music are not identical. There are separate
audiences, of widely differing tastes and musical receptivity, for opera,
symphony and chamber music. The oratorio audience is a very special group made
up of the most conservative tastes and opinions. One suspects that it is
recruited largely from friends and families of the singers. Now a stage full of
happy and earnest oratorio singers must represent considerable potential ticket
sales, and, if this is true, it does not malt much difference what work the
singers select to perform. Anyone who has ever sung in a chorus knows what fun
it is to sing Handel. The music is easy to grasp, fits the voice well, and fine
effects are achieved with a minimum of professional skill. The plan of the
Handel oratorio is ideal for the ordinary amateur singing group. All the hard
parts are taken by professional soloists, who can be imported for the occasion.
Therefore the chorus can make a public appearance after long, leisurely
preparation and add on at the last moment the final professional touches. Thus
the never-ending vogue of the oratorio and its unchanging aspect must be
attributed, at least partially, to the amateur choral societies that are to be
found in almost every community. What can be concluded form the passage about the characteristics of oratorios
A．They are primarily performed by professionals. B．They vary little from one performance to another. C．They are composed entirely of solos. D．They are carelessly scheduled.
