One of the reasons that new works of classical music don’t turn up more often on the programs of smaller orchestras is that they’re damned expensive. Commissioning a new work from an established composer can cost tens of thousands of dollars, and few ensembles outside of the top orchestras have that kind of cash to kick around (and if they did, they’d likely have more important things to spend it on.) But this week, a new work by composer Joan Tower will get its premiere, courtesy of a first-of-its-kind commissioning program that brought together no fewer than 65 small orchestras from across the U.S. to fund the creation of the work. The composer will see an added benefit from the unusual process as well: when all is said and done, her new work will have been performed 80 times over the course of 18 months.
