Input: Article: In the 19th century, musical institutions emerged from the control of wealthy patrons, as composers and musicians could construct lives independent of the nobility. Increasing interest in music by the growing middle classes throughout western Europe spurred the creation of organizations for the teaching, performance, and preservation of music. The piano, which achieved its modern construction in this era (in part due to industrial advances in metallurgy) became widely popular with the middle class, whose demands for the instrument spurred a large number of piano builders. Many symphony orchestras date their founding to this era. Some musicians and composers were the stars of the day; some, like Franz Liszt and Niccolo Paganini, fulfilled both roles.

Now answer this question: What class increased it's interest in music during the 19th century?

Output: middle classes

Article: In 586 BCE King Nebuchadnezzar II of Babylon conquered Judah. According to the Hebrew Bible, he destroyed Solomon's Temple and exiled the Jews to Babylon. The defeat was also recorded by the Babylonians (see the Babylonian Chronicles). In 538 BCE, Cyrus the Great of Persia conquered Babylon and took over its empire. Cyrus issued a proclamation granting subjugated nations (including the people of Judah) religious freedom (for the original text, which corroborates the biblical narrative only in very broad terms, see the Cyrus Cylinder).

Here is a question about this article: "Hanover" is the traditional English spelling. The German spelling (with a double n) is becoming more popular in English; recent editions of encyclopedias prefer the German spelling, and the local government uses the German spelling on English websites.

The traditional English spelling is still used in historical contexts, especially when referring to the British House of Hanover.
