With an upbringing in a musical family, Krishna Tithi's involvement with the art form began when she was three years old. She trained under the tutelage of her father, Tapash Kumar Khan, a renowned singer at Bangladesh Television and Bangladesh Betar. Tithi came under the limelight after securing a position amongst the top four contestants in Channel i's reality show, Shera Kontho in 2009. The following year, she emerged as the winner in another competition titled, Sherader Moha Juddho on Channel i. She continued to pursue her passion for music, performing and competing at various national and international programmes, garnering admiration.
Currently a resident of New York, USA, Tithi is not allowing the distance from Bangladesh to affect the devotion she nurtured at home for the art. Despite her challenging profession as a business analyst at a financial company, the singer continues to remain committed to her music. Since her school days, Tithi bagged several awards and earned much recognition for her musical aptitude. Later, she also received a Special Congressional Recognition from the United States House of Representatives for her outstanding and invaluable service to the community.
