Writing in 1869 for a popular readership, Edgar Brinsmead says "...hence the necessity of _tempering_ the fourths and fifths which has given the new scale the name of equal temperament". He then goes on for a page or so describing exactly how the scale is laid though without going into the actual number of beats involved, which would have been beyond the scope of his little book. By "new" he means since 1841-46, when equal temperament was commercially established in England and when Broadwood and the other main makers would have started regularly using it. The evidence is well documented by Alexander Ellis, the translator (1885) of Helmholtz's Sensations of Tone (Dover Books). Equal temperament was by this time well established in Germany. Helmholtz himself writes (1862) "Of our great composers, Mozart and Beethoven were yet at the beginning of the reign of equal temperament". According to Ellis: "In 1812 Dr Crotch (Elements of Musical Composition, pp 134-5) gives the proper figures for equal temperament....but says nothing to recommend it. Yet in 1840 Dr. Crotch had his own chamber organ tuned in equal temperament." From what I read, I gather that England was some way behind Germany, and probably France, in the matter of equal temperament and it seems likely that the knowledge was available to tune accurately in ET very early in 19th century. Scheibler, the inventor of the tonometer that allowed perfect tuning in ET, died in 1837. It seems to me highly unlikely that Chopin would have been happy playing his compositions on a piano that was not equally tempered and I for one would not want to hear them. I'm not interested in joining this debate, but the very detailed facts and figures are there for anyone to read. As to the relative skills of tuners now and 150 years ago, I'd guess the avant-garde then were as good as the best now. I can't think of a single reason why they should not have been. JD
