Tatiana Iashvili was born on January 4th, 1980, in Severodonetsk, Luhansk region of Ukraine, into a family of professional musician. She finished her choral and vocal studies with honours at a music school. Her first works were written during that period and included a song cycle, piano miniatures and arrangements, and adaptation of folk songs.
In 1999, she graduated with honours from the Music Theory Department of the Higher Prokofiev Music College. She won regional youth competitions in music theory and history twice, in 1995 and 1996. Her teachers included T. Dugina (composition, harmony, polyphony, and analysis of musical works) and A. Strus (instrumentation).
In 1998, Tatiana Iashvili became a parishioner and chanter of an Orthodox cathedral.
During 1999-2005, she was studying composition at National Tchaikovsky Academy of Music in Kyiv (Class of Prof. Ihor Shcherbakov). Her teachers were H. Lyashenko (polyphony), Yu. Ishchenko (history of orchestral styles), L. Kolodub (instrumentation), N. Kovalinas (harmony and analysis), and H. Havrylets (choral arrangement).
Her most significant works of that period were the Piano Sonata №1 (2001), Glare string trio (2001), Songs of Tenderness for a capella choir (2002), Sofia! for (2003), Time for string orchestra (2003), the Symphonic Poem (2005), and some liturgical chants.
At the same time, she studied the Orthodox singing tradition and its origins as well as the features of the ancient Russian Znamenny chant, Byzantine and Georgian singing. Her understanding of choral aesthetics was greatly enhanced through the lectures on Liturgics given by Deacon Dmitry Bolgarskiy in Conservatory and his classes of Znamenny chant.
