"The MIMO (Musical Instrument Museums Online) project has created a single access point to digital content and information on the collections of musical instruments held in a consortium of European museums. (...) The MIMO project has also involved the revision of the Hornbostel Sachs classification of musical instruments, with the main aim of classifying instruments such those in the new Electrophones class 5, invented since the publication of the original scheme of 1914 by Erich M. von Hornbostel and Curt Sachs. A number of scholars have at various times revised or extended the scheme. The MIMO consortium’s version is closely based on the revised version (classes 1-4) by Jeremy Montagu to whom the consortium owes a debt of gratitude for generously sharing with us with us all resources associated with it; (...). This version of classification has been incorporated within the databases of a number of the museums in the MIMO project."
