Answer the question at the end by quoting:

Anton Grigorevich Rubinstein (Russian: Anton Grigor'evich Rubinshtein, tr. Anton Grigorevich Rubinshteyn; November 28 [O.S. November 16] 1829 - November 20 [O.S. November 8] 1894) was a Russian pianist, composer and conductor who became a pivotal figure in Russian culture when he founded the Saint Petersburg Conservatory. He was the elder brother of Nikolai Rubinstein who founded the Moscow Conservatory. As a pianist, Rubinstein ranks among the great 19th-century keyboard virtuosos.
Rubinstein was born to Jewish parents in the village of Vikhvatinets in the Podolia Governorate, Russian Empire (now known as Ofatinti in Transnistria, Republic of Moldova), on the Dniestr River, about 150 kilometres (93 mi) northwest of Odessa. Before he was 5 years old, his paternal grandfather ordered all members of the Rubinstein family to convert from Judaism to Russian Orthodoxy. Although he was raised as a Christian, Rubinstein would later return to being atheist.  Rubinstein's father opened a pencil factory in Moscow. His mother, a competent musician, began giving him piano lessons at five, until the teacher Alexander Villoing heard and accepted Rubinstein as a non-paying student. Rubinstein made his first public appearance at a charity benefit concert at the age of nine. Later that year Rubinstein's mother sent him, accompanied by Villoing, to Paris where he sought unsuccessfully to enroll at the Paris Conservatoire.  Rubinstein and Villoing remained in Paris for a year. In December 1840, Rubinstein played in the Salle Erard for an audience that included Frederic Chopin and Franz Liszt. Chopin invited Rubinstein to his studio and played for him. Liszt advised Villoing to take him to Germany to study composition; however, Villoing took Rubinstein on an extended concert tour of Europe and Western Russia. They finally returned to Moscow in June 1843. Determined to raise money to further the musical careers of both Anton and his younger brother Nikolai, their mother sent Rubinstein and Villoing on a tour of Russia, following which the brothers were dispatched to Saint Petersburg to play for Tsar Nicholas I and the Imperial family at the Winter Palace. Anton was 14 years old; Nikolai was eight.

What were his early experiences with music?

His mother, a competent musician, began giving him piano lessons at five, until the teacher Alexander Villoing heard and accepted Rubinstein as a non-paying student.

IN: Pitchford was born in Honolulu, where he attended Catholic schools, graduating in 1968 from Saint Louis High School. He began his performance career as an actor and a singer with the Honolulu Community Theatre (now Diamond Head Theatre), the Honolulu Symphony Orchestra and the Honolulu Theatre for Youth, among others. While studying at Yale University, Pitchford performed with numerous campus drama groups, but his focus gradually turned off-campus, where he worked with the Wooster Square Revival, an experimental theatre company that offered acting opportunities to recovering addicts and alcoholics. In 1969, Pitchford returned to Honolulu as an assistant to authors Faye Hammel and Sylvan Levey in updating the popular guidebook Hawai'i on $5 and $10 A Day, and researching Trans World Airlines' Budget Guide to Hawai'i, the first of a series of guidebooks that would eventually turn into the popular series TWA Getaway Guides.

As a result of performing his early songwriting efforts in cabarets around Manhattan, he was invited to write with such composers as Stephen Schwartz, Alan Menken and Rupert Holmes. In 1979, he collaborated with recording artist and cabaret performer Peter Allen to write new songs for Allen's one-man Broadway revue, Up In One.  With composer Michael Gore, Pitchford collaborated on three songs for Alan Parker's 1980 motion picture Fame; these were "Red Light," a disco hit for singer Linda Clifford; the symphonic/rock finale "I Sing the Body Electric;" and the title song "Fame," which became a multi-platinum, international best seller for Irene Cara. That song earned Gore and Pitchford an Oscar, a Golden Globe, and a Grammy nomination for Song of the Year (1981). They also received a Grammy nomination for Best Soundtrack Album for a Motion Picture, Television or Other Visual Media.  When Pitchford was signed by Warner Brothers Publishing (1981) he began collaborating with a variety of songwriters. Among the first songs whose lyrics he wrote in collaboration with composer Tom Snow was "Don't Call It Love," which was first recorded by Kim Carnes on her 1981 album Mistaken Identity; the selection charted in the U.S. country singles top-ten for Dolly Parton in 1985 and was named the BMI Country Song of the Year.  For the ill-fated 1981 movie The Legend of the Lone Ranger, Pitchford wrote a narrative ballad, "The Man In the Mask." This was spoken (throughout the movie) and sung (at its beginning and end) by Merle Haggard.  "You Should Hear How She Talks About You," another Snow/Pitchford composition, was a Top 5 hit for Melissa Manchester for which she won the Grammy Award for Best Female Pop Vocal Performance in 1983. That same year, Pitchford, Kenny Loggins and Steve Perry wrote and composed "Don't Fight It," a Top 20 hit that was Grammy-nominated in the Best Pop Vocal Duo category. With musical director Michael Miller, he wrote the theme song for the weekly dance-music show Solid Gold (1980-88).
