Please answer this: The answer to the question: What is the last name of the person who entered the Conservatoire de Paris before he was six? is inside the article: Charles-Valentin Alkan (French: [al valt alk]; 30 November 1813 29 March 1888) was a French-Jewish composer and virtuoso pianist. At the height of his fame in the 1830s and 1840s he was, alongside his friends and colleagues Frederic Chopin and Franz Liszt, among the leading pianists in Paris, a city in which he spent virtually his entire life. Alkan earned many awards at the Conservatoire de Paris, which he entered before he was six. His career in the salons and concert halls of Paris was marked by his occasional long withdrawals from public performance, for personal reasons. Although he had a wide circle of friends and acquaintances in the Parisian artistic world, including Eugene Delacroix and George Sand, from 1848 he began to adopt a reclusive life style, while continuing with his compositions virtually all of which are for the keyboard. During this period he published, among other works, his collections of large-scale studies in all the major keys (Op. 35) and all the minor keys (Op. 39). The latter includes his Symphony for Solo Piano (Op. 39, nos. 47) and Concerto for Solo Piano (Op. 39, nos. 810), which are often considered among his masterpieces and are of great musical and technical complexity. Alkan emerged from self-imposed retirement in the 1870s to give a series of recitals that were attended by a new generation of French musicians. Alkan's attachment to his Jewish origins is displayed both in his life and his work. He was the first composer to incorporate Jewish melodies in art music. Fluent in Hebrew and Greek, he devoted much time to a complete new translation of the Bible into French. This work, like many of his musical compositions, is now lost. Alkan never married, but his presumed son Elie-Miriam Delaborde was, like Alkan, a virtuoso performer on both the piano and the pedal piano, and edited a number of the elder composer's works. Following his death (which according to persistent but unfounded legend was caused by a falling bookcase) Alkan's music became neglected,..., can you guess it ?

Problem: The answer to the question: What is the stage name of the person who attended the Convent of the Sacred Heart at age 11? is inside the article: Stefani Joanne Angelina Germanotta was born on March 28, 1986 at Lenox Hill Hospital in Manhattan, New York City, to a Catholic family. Her parents both have Italian ancestry; she also has more distant French-Canadian roots. Her parents are Cynthia Louise (nee Bissett) and Internet entrepreneur Joseph Germanotta, and she has a younger sister, Natali. Brought up in the Upper West Side of Manhattan, Gaga says that her parents came from lower-class families and worked hard for everything. From age 11, she attended the Convent of the Sacred Heart, a private all-girls Roman Catholic school. Gaga described her high school self as "very dedicated, very studious, very disciplined" but also "a bit insecure". She considered herself a misfit and was mocked for "being either too provocative or too eccentric".Gaga began playing the piano at age four when her mother insisted she become "a cultured young woman". She took piano lessons and practiced through her childhood. The lessons taught her to create music by ear, which she preferred over reading sheet music. Her parents encouraged her to pursue music, and enrolled her in Creative Arts Camp. As a teenager, she played at open mic nights. Gaga played the lead roles of Adelaide in Guys and Dolls and Philia in A Funny Thing Happened on the Way to the Forum at a nearby boys' high school. She also studied method acting at the Lee Strasberg Theatre and Film Institute for ten years. Gaga unsuccessfully auditioned for New York shows, though she did appear in a small role as a high school student in a 2001 episode of The Sopranos titled "The Telltale Moozadell". She later said of her inclination towards music: I don't know exactly where my affinity for music comes from, but it is the thing that comes easiest to me. When I was like three years old, I may have been even younger, my mom always tells this really embarrassing story of me propping myself up and playing the keys like this because I was too young and short to get all the way up there. Just go like this on the low end of..., can you guess it ?

A: Gaga
Q: The answer to the question: What is the last name of the person who allied himself with the German emperor Lothair III? is inside the article: Alexios's son John II Komnenos succeeded him in 1118 and ruled until 1143. John was a pious and dedicated Emperor who was determined to undo the damage to the empire suffered at the Battle of Manzikert, half a century earlier. Famed for his piety and his remarkably mild and just reign, John was an exceptional example of a moral ruler at a time when cruelty was the norm. For this reason, he has been called the Byzantine Marcus Aurelius. During his twenty-five-year reign, John made alliances with the Holy Roman Empire in the West and decisively defeated the Pechenegs at the Battle of Beroia. He thwarted Hungarian and Serbian threats during the 1120s, and in 1130 he allied himself with the German emperor Lothair III against the Norman king Roger II of Sicily.In the later part of his reign, John focused his activities on the East, personally leading numerous campaigns against the Turks in Asia Minor. His campaigns fundamentally altered the balance of power in the East, forcing the Turks onto the defensive, while restoring many towns, fortresses, and cities across the peninsula to the Byzantines. He defeated the Danishmend Emirate of Melitene and reconquered all of Cilicia, while forcing Raymond of Poitiers, Prince of Antioch, to recognise Byzantine suzerainty. In an effort to demonstrate the Emperor's role as the leader of the Christian world, John marched into the Holy Land at the head of the combined forces of the Empire and the Crusader states; yet despite his great vigour pressing the campaign, his hopes were disappointed by the treachery of his Crusader allies. In 1142, John returned to press his claims to Antioch, but he died in the spring of 1143 following a hunting accident., can you guess it ?
A:
Komnenos
