In 1855 he accepted an invitation to London, where he conducted the concerts of the Philharmonic Society with great success.
Among musical organizations may be mentioned the Handel and Haydn Society (1815), the Harvard Musical Association (1837), the Philharmonic (1880) and the Symphony Orchestra, organized in 1881 by the generosity of Henry Lee Higginson.
But the Philharmonic Society adopted the Diapason Normal in 1896, and the military bands have not gone with it.
From 1892 to 1899 he conducted the Philharmonic Concerts, and was knighted in 1894.
Stein tuned Mozart's piano to a fork a' 421.6, and the Broadwood pianos used at the London Philharmonic Society in its first concerts (1813) were tuned to a fork c 2 506.8, which gives a mean tone a' 423.7.
About that time, or it may be a few years earlier, Sir George Smart established a fork for the Philharmonic Society, a' 433.2.
The British army is bound by His Majesty's Rules and Regulations to play at the Philharmonic pitch, and a fork tuned to a' 452.5 in 1890 is preserved as the standard for the Military Training School at Kneller Hall.
No one of these works is now known to be in existence; the only example we possess of Zarlino's compositions on a grand scale is a MS. mass for four voices, in the library of the Philharmonic Lyceum at Bologna.
