Experimental Musical Instruments was a periodical edited and published by Bart Hopkin, a leader in 20th century experimental music design and custom made instrument construction. Though no longer in print, back issues are still available. The material and approach of EMI can now be found electronically on their site hosted by Bart Hopkin. This site is, together with www.oddmusic.com the main source on the internet for experimental musical instrumentalism.
Although only old editions of the magazine are still available and no newer editions appear, the name is still in use as the publisher for many of the book written by Bart Hopkin and co-writers.
