I bought this book in July and am still reading it, though I am now more than halfway through it. Like any biography of this size, Cairns occasionally runs into the "and then he wrote....and then he played..." syndrome, and to be honest, after a while each struggle to pull together an orchestra and interest an audience reads like each previous instance. On the other hand, it dispels many myths about Berlioz and his acceptance in his time, among them the fact that he never really stopped loving Harriet or her artistic soul even after her descent into alcoholism, delusions and strokes. It also shows that Berlioz did indeed have his champions, even in Paris where he also had enemies, based solely on the fact that his music was multi-rhythmic and therefore hard to follow! Among the many champions of his music were the Germans, Austrians and Russians, but especially the Hungarians and British, who heard and appreciated the great and wonderful things in his music.
The person one feels sorriest for is his son Louis, born into a marriage that Berlioz' father and sisters opposed, sent to boarding school when his mother descended into alcoholism and madness, seldom receiving the bonding love of his all-too-busy father. We also learn that Berlioz purposely suppressed inspirations to compose symphonies because he couldn't afford to perform them, and he wanted to use the money to help set up his son as a sailor.
Best of all, however, we get a VERY realistic glimpse into the performing world of the early-to-late 19th century, in which composers had to foot the bill for the performance (and copying) of their own works, playing to half-filled houses and often losing money on their ventures. We also learn of the strengths and weaknesses of the various musical centers of Europe, particularly the weaknesses, so much so that the composer often deleted movements from his symphonies and masses because the performers could not play them correctly. Thus the "golden age" of the Romantic era is dispelled as a myth propagated by rumor and hearsay. The reality is far less sunny, making us realize that even then art music struggled to find an audience and be appreciated.
Most of all, one suffers along with Berlioz, feels his angst and anguish as he struggles time and again to establish and re-establish himself in the face of organized, official opposition. Yes, there were critics and audiences who did recognize his genius and love his music, cruel reviews and nasty caricatures to the contrary, and this acceptance was much more widespread among lay listeners than we have been led to believe. Berlioz was cheered, mobbed and loved by practically every European culture center EXCEPT Paris, and even there he had his partisans....just never enough to keep him afloat financially or help him get his music produced.
If you love classical music and enjoy Berlioz, this is a recommended read.....just go slowly, don't try to speed-read through it, and you will get a lot more out of it.
