If you’ve ever entertained the notion of commissioning your very own piece of music, now there’s a guide to help you out. Published by the composer advocacy group, Meet the Composer, the booklet tells of the experiences of others who have commissioned works and offers a pricing guide (solo or duo work: between $2,000 and $20,000, depending on the length, full-length opera: $465,000 or more). It’s just the thing for that fabled someone who has everything.
