I collaborated with digital artist Ed Holroyd to create an online version of the Music Box Migrations workshop that accompanies my Piano Migrations installation.
You can go to the site here, type in a start and and end location (make sure you include the country too). You can then press play and it will follow the google maps route instructions, playing a music box note each time there is an instruction to follow. You can personalise the settings by selecting different start notes and scales to use.  If you select ‘avoid major highways’ the route will change and you will get a different tune.
