match in 1914, and Mikhail Botvinnik, with whom he played several matches in the 1930s. At age nine, he was composing his first opera, The Giant, as well as an overture and various other pieces. Education and early works In 1902, Prokofiev's mother met Sergei Taneyev, director of the Moscow Conservatory, who initially suggested that Prokofiev should start lessons in piano and composition with Alexander Goldenweiser. Unable to arrange that, Taneyev instead arranged for composer and pianist Reinhold Glière to spend the summer of 1902 in Sontsovka teaching Prokofiev. The first series of lessons culminated, at the 11-year-old Prokofiev's insistence, with the budding composer making his first attempt to write a symphony. The following summer, Glière revisited Sontsovka to give further tuition. When, decades later, Prokofiev wrote about his lessons with Glière, he gave due credit to his teacher's sympathetic method but complained that Glière had introduced him to "square" phrase structure and conventional modulations, which he subsequently had to unlearn. Nonetheless, equipped with the necessary theoretical tools, Prokofiev started experimenting with dissonant harmonies and unusual time signatures in a series of short piano pieces he called "ditties" (after the so-called "song form", more accurately ternary form, on which they were based), laying the basis for his own musical style. Despite his growing talent, Prokofiev's parents hesitated over starting their son on a musical career at such an early age, and considered the possibility of his attending a good high school in Moscow. By 1904, his mother had decided instead on Saint Petersburg, and she and Prokofiev visited the then capital to explore the possibility of moving there for his education. They were introduced to composer Alexander Glazunov, a professor at the Saint Petersburg Conservatory, who asked to see Prokofiev and his music; Prokofiev had composed two more operas, Desert Islands and The Feast during the Plague, and was working on his fourth, Undina. Glazunov was so impressed that he urged Prokofiev's mother to have her son apply for admission to the Conservatory. He passed the introductory tests and enrolled that year. Several years younger than most of his class, Prokofiev was viewed as eccentric and arrogant, and annoyed a number of his classmates by keeping statistics on their errors. During that period, he studied under, among others, Alexander Winkler for piano, Anatoly Lyadov for harmony and counterpoint, Nikolai Tcherepnin for conducting, and Nikolai Rimsky-Korsakov for orchestration (though when Rimsky-Korsakov
