Fidelity is the quality of being faithful or loyal. Its original meaning regarded duty to a lord or a king, in a broader sense than the related concept of fealty. Both derive from the Latin word fidēlis, meaning "faithful or loyal".

In modern human relationships, the term can refer to sexual monogamy. In western culture this often means adherence to marriage vows, or of promises of exclusivity or monogamy, and an absence of adultery. However, some people do not equate fidelity in personal relationships with sexual or emotional monogamy. (For example, see polyamory and Open marriage.) Often, however, females in Shakespeare are associated with it in a negative sense, such as "She is with little fidelity". For example, Bertram accuses Helena of having "little fidelity" in All's Well That Ends Well.

Fidelity also denotes how accurate a copy is to its source. For example, a worn gramophone record will have a lower fidelity than one in good condition, and a recording made by a low budget record company in the early 20th century is likely to have significantly less audio fidelity than a good modern recording. In the 1950s, the terms "high fidelity" or "hi-fi" were popularized for equipment and recordings which exhibited more accurate sound reproduction. The converse term "lo-fi", doesn't necessarily mean "low fidelity", rather that the production ethic aims for "gritty authenticity" over perfect production. Similarly in electronics, fidelity refers to the correspondence of the output signal to the input signal, rather than sound quality.

Regina Ilyinichna Spektor (Russian: Реги́нa Ильи́нична Спе́ктор, IPA: [rʲɪˈɡʲinə ˈspʲɛktər], English: /rɨˈdʒiːnə ˈspɛktər/; born February 18, 1980) is an American singer-songwriter and pianist. Her music is associated with the anti-folk scene centered in New York City's East Village.

Spektor was born in Moscow, Soviet Union in 1980 to a musical Russian Jewish family. Her father, Ilya Spektor, is a photographer and amateur violinist. Her mother, Bella Spektor, was a music professor in a Soviet college of music and now teaches at a public elementary school in Mount Vernon, New York. She has a brother Barry (Bear), who was featured in track 7, "* * *", or "Whisper", of her 2004 album, Soviet Kitsch.

She learned how to play piano by practising on a Petrof upright that was given to her mother by her grandfather. She was also exposed to the music of rock and roll bands such as The Beatles, Queen, and The Moody Blues by her father, who obtained such recordings in Eastern Europe and traded cassettes with friends in the Soviet Union. The family left the Soviet Union in 1989, when Regina was nine and a half, during the period of Perestroika, when Soviet citizens were permitted to emigrate. Regina had to leave her piano behind. The seriousness of her piano studies led her parents to consider not leaving the USSR, but they finally decided to emigrate, due to the ethnic and political discrimination that Jews faced. Spektor is fluent in Russian and reads Hebrew, and has since paid tribute to her Russian heritage, quoting the poem February by the Russian poet Boris Pasternak in her song Après Moi, and stating “I’m very connected to the language and the culture.”
