The percentage of the population in the United States that actually listens to classical music is not high. There are many reasons for this, but among them surely must be the cost of concerts; even 'cheap' tickets can be fifteen or twenty dollars, which, multiplied by four (for a family) and with parking thrown in, can easily bring the cost of attending a single concert to close to a hundred dollars. Where the interest in music does not already exist, even families which can afford this will not be likely to spend it; those without such extra money won't even consider attending said concert. Yet live performances are among the most surefire ways to engage people, with many a music lover testifying to the impact of a concert heard when they were young.
So here's an idea for addressing this problem: the creation and permanent funding of regional touring orchestras (as my first sentence should suggest, this is aimed primarily at the situation in the U.S., but it could be adapted for other countries as well, if necessary). These would be fully professional orchestras which would give two free concerts a weekend (Saturday night and Sunday afternoon), performing in a different location within their region (the regions being defined by population so as to be roughly equal) each weekend.
How much would this cost? Well, that would depend, but let's assume that each orchestra has 70 permanent members (12 first/ 12 second violins, 10 violas, 8 violoncellos, 5 basses; 2 each of flute, oboe, clarinet, bassoon; 3 trumpets, 4 horns, 3 trombones, tuba; harp; timpani & 2 percussion). Each player receives 40,000.00/year in salary and benefits (not as good as the top orchestras, but better than many smaller but fully professional ones). And let's assume that there are fifty such orchestras, one for each state (obviously this is more than the regional scenario requires, but it's always better to aim high when considering expenses), for a total of 3,500 players. The salary/benefit cost would thus come to 140 million dollars a year for players, and probably another 4 million for support staff. Add travel, food, and lodging: assuming 200.00/night for 52 nights a year, which is a very high rate indeed, you arrive at about 37 million dollars (though over time you could also construct lodging for the players in the various locations). With a conductor's salary (call that 200,000.00/year), and commissioning fees for a number of new works each year, and rounding up very generously, the total annual cost of fifty (50!) touring orchestras would be 200 million dollars. That is not very much, and--
-- the benefits would be incalculable; literally millions of people, many of whom will never have heard a live orchestra in their entire lives, would be able to attend excellent concerts for free. There would be economic benefits as well. Young musicians would suddenly have real opportunities to perform (the very first thing this project would do would be to create thousands of jobs), and they would, of course, be spending money in many of the locations visited, creating a financial ripple effect. The increased interest in good music among audience members would lead to increased CD sales, and so on. There are no downsides to this idea, so far as I can see.
The only thing I can't see in this picture is the political will. Unfortunately, among those least interested in serious music (or the arts in general) are far too many of our elected representatives. Changing that, though, may be the most difficult aspect of this whole plan....
