Tim Blanning's social and cultural history of the advance of music as an art form, starting from the late 17 and early 18th Centuries is quite an achievement, mainly in the sense that to cover both Classical and Modern music (leading to 2009 when the book was written) is no easy task for a book around 400 pages deep. The history is packed to the brim with anecdotes, facts as well as being a social commentary on the role music has played in the formation of the modern world. It is not easy to write about classical composers and how important they were in shaping nationalist pride in countries such as Italy, Germany, Russia - they helped form the nation state in the sacralisation of, possibly, an 'imagined' community that gave pride in being 'Italian' or 'German' using the medium of Operas and so on, and then finish each chapter with developments in modern music, or at least from the second half of the twentieth century onwards.
The book details the role music has played throughout modern history, starting from when Monarchies employed Composers such as Handle, Haydn, Mozart et al for their own personal use, then slowly the architectural growth of Opera Houses and the democratisation of music being available to anyone who could afford to attend a performance. From being 'elitist' to becoming a mass cultural phenomena, starting with the status of composers such as Listz and Paganini being the first 'Rock Gods', whom became more popular and more famous than various European Monarchies, as well as the shift away from music being used for solely religious purposes into a mass social 'market' (and very often in modern times anti religious) then the transformation is massive and Tim Blanning manages to cover it all. One could doubt how both Italian and German Unification towards the latter half of the 19th Century would have fared without Operas invoking (imagined) 'nationalist' sentiments and the mass appeal musical public performances held. We can take this to the 20th Century and role Jazz, R'n'B and early Rock n' Roll played in creating an identity amongst the Black Civil Rights movement of the 1960's, and not just exclusively amongst blacks either; many liberation causes are tied up with sub-cultures and a musical identity today. Also, technology wise, the development of the Piano was integral to the democratisation of music, allowing anyone with some money to learn how to play. Compare that to today - we have electronics and home stereo systems that allow us to listen to music, but during the 19th Century one had to learn musical notation in order to perform the latest symphony or opera for personal recreational use.
Tim Blannings social and cultural history of the development of music as an art-form, a mass market one at that, focuses I believe slightly too much on the Classical composers in each chapter, with a few pages at the end of each bringing it up to date to modern times. He does however spend some pages explaining Jazz and liberation movements of the 20th Century and how vital music is and was to personal identity, compared to the old national identity of the 19th Century. I believe there is a room for separate studies on all what it touched on here; both the technology aspect - from piano to electronics and amplification as well as modern day identity politics and sub-cultures and the music associated with them.
