The Signature Series by producer Paolo Pietropaolo (host of In Concert on CBC Radio 2) and co-producer Denise Ball is a music program that explores the personality behind key signatures of music by personifying each of the 24 keys as a person. In 2013, Pietropaolo won the Prix Italia in the category of best work for music for the program.
The Signature Series started when the first post on CBC Music was posted on 18 May 2012. It was a preview of what was coming up in the weeks ahead. The first episode, "G minor: The Contrarian", was posted online on 21 June 2012.[citation needed]
