Her father died before she was born, and after her mother's death from typhoid fever when she was one and a half years old, she was raised by her grandmother, rowzeh-khân (singer of soaz) at the darbar of Naser al-Din Shah Qajar, Mollâ Khayr-ol-Nesâ' Eftekhâr-ol-Zâkerin (the latter name was bestowed on her by the king, meaning "Glory of the Narrators").

During another performance at the Palace Theater in Tehran, again without the veil, she was accompanied by Morteza Neidavoud, who she had met when she was 16, just a few years earlier.

Her existing birth certificate, issued in Tehran in 1925, legally records her first name as "Qamar-ol-Moluk" and her last name as changed from "Seyed Hosayn Khân" to "Vazirizâdeh", a name she chose for herself in honor of the musician and theoretician of music Ali-Naqi Vaziri.

[2] Vaziri retired from singing in 1956, having worked for over 30 years with songwriters and poets in Iran, such as Morteza Neydavud, and having been recorded on several gramophone discs.

She devoted her last years to philanthropic activities, as Zobeideh Jahangiri recalls them in A Moon Which Became The Sun (Persian: قمری که خورشید شد / Qamar-i Keh Xoršid Šod).
