Guide to the Incorporated Society of Musicians & Musicians’ Union?


The Incorporated Society of Musicians (ISM) is the UK’s Professional Body for Musicians and the Musicians’ Union (MU) is the UK’s union for musicians. This blog post lays out a few of the differences between the two. Encore does not advise membership in one organisation over the other. The ISM and MU websites each have a great deal of helpful information which we encourage you to explore.

First, a few words about why it’s important to be in a union or professional body. It can help you by providing public liability insurance, discounts on instrument insurance, help with negotiating contracts, and assistance if you are injured or ill. They are also important voices in lobbying the government for arts-friendly policies and raising awareness about fair working conditions and pay for musicians.
