The RASC's transit of Venus website  now features the web premier of a piece of new/old transit of Venus (ToV) music. Ever wondered where all the 17th-18th century ToV themed music is? There's some evidence that it might have been part of the casual improvisatory musical culture of the time. Wonder what that would sound like? The RASC Archivist has created an example  based on the bass pattern of a dance from John Blow's Venus and Adonis (1683). You can hear him play it on a type of instrument which would have been familiar to Edmund Halley.
