Problem: Ottoman Empire:

Ottoman classical music was an important part of the education of the Ottoman elite, a number of the Ottoman sultans were accomplished musicians and composers themselves, such as Selim III, whose compositions are often still performed today. Ottoman classical music arose largely from a confluence of Byzantine music, Armenian music, Arabic music, and Persian music. Compositionally, it is organised around rhythmic units called usul, which are somewhat similar to meter in Western music, and melodic units called makam, which bear some resemblance to Western musical modes.

The sultan known by what name has compositions which are still performed today?

Problem: Polish composers of the following generation included virtuosi such as Moritz Moszkowski, but, in the opinion of J. Barrie Jones, his "one worthy successor" among his compatriots was Karol Szymanowski (18821937). Edvard Grieg, Antonin Dvorak, Isaac Albeniz, Pyotr Ilyich Tchaikovsky and Sergei Rachmaninoff, among others, are regarded by critics as having been influenced by Chopin's use of national modes and idioms. Alexander Scriabin was devoted to the music of Chopin, and his early published works include nineteen mazurkas, as well as numerous etudes and preludes; his teacher Nikolai Zverev drilled him in Chopin's works to improve his virtuosity as a performer. In the 20th century, composers who paid homage to (or in some cases parodied) the music of Chopin included George Crumb, Bohuslav Martinu, Darius Milhaud, Igor Stravinsky and Heitor Villa-Lobos.
Many people were considered influenced by Chopin's what?
