COGITCH stands for COgnition Guided Interoperability beTween Collections of musical Heritage. The name also refers to the ‘cognitive itch’ that is caused by ‘earworms’: fragments of music that you cannot get out of your head, no matter how hard you try. Musical salience and memorability of musical fragments play an important role in COGITCH.

In COGITCH valuable collections of music are made interoperable and researched. These are the Dutch folk songs from the Dutch Song Database of the Meertens Institute, especially the field recordings known as “Onder de groene linde”, and early recordings of Dutch popular music from the Netherlands Institute for Sound and Vision. The interoperability will enable musicological research into the evolution of song culture. 

COGITCH is financed by the NWO CATCH programme.
