German-Sorbian musician and composer Carolina Eyck was introduced to the theremin by her parents at the age of 7. She took her first theremin lessons with Lydia Kavina.

After her debut in the Berlin Philharmonie in 2002 she has been invited to concerts and festivals around the world. It was not long before she was known as one of the best theremin soloists worldwide.

At the age of 16, Carolina developed a new precise playing technique, called the 8 finger position technique. She published the first extensive theremin method book entitled The Art of Playing the Theremin in 2006.

With this technique the player is able to tune the theremin to their hand and rely on their finger positions, rather than correcting notes after they are audible. This method is now being used by thereminists around the world and has revolutionized how the instrument is played.

Over the years, Carolina has collaborated with various musicians, conductors, ensembles, and symphony orchestras, including Fazil Say, Heinz Holliger, Michael Sanderling, Gürer Aykal, and Brad Lubman; the Berlin Radio Symphony Orchestra, Dresden Philharmonic, Bern Symphony Orchestra, San Francisco Ballet Orchestra, Argentine National Symphony Orchestra, Brussels Philharmonic, National Symphony Orchestra (Washington D.C.), and Mozarteum Orchestra Salzburg.

Carolina has performed in concert halls around the world, including the Walt Disney Concert Hall in Los Angeles, the Kennedy Center for the Performing Arts in Washington D.C., MONA (Museum of New and Old Art) Tasmania, Konzerthaus Berlin, Bozar Brussels, Rudolfinum in Prague, Großes Festspielhaus Salzburg, Centro Cultural Kirchner (CCK) Buenos Aires, Teatro National de Guatemala, and Centro Gabriela Mistral Santiago, Chile.

Since 2013, she has performed with pianist and composer Christopher Tarnow as a duo. In October 2015, they published an album with contemporary compositions for theremin and piano, Theremin Sonatas. In 2016, Carolina released an album with her own composition Fantasias for Theremin and String Quartet with the American Contemporary Music Ensemble (ACME).

Carolina has premiered a number of works, among others:
• Jan Bilk - Stigma Integrum for Theremin and String Quintet (2007)
• Andrew Norman - Theremin Concerto Air (2011)
• Fazil Say - Symphonies Mesopotamia and Universe (2012)
• Kalevi Aho - Theremin Concerto Eight Seasons (2012)
• Christopher Tarnow - 1st and 2nd Theremin Sonata (2013, 2014)
• Carolina Eyck - Fantasias for Theremin and String Quartet (2015)
• Régis Campo - Dancefloor With Pulsing (2018)

In 2006, Carolina won the International Competition for Composers arranged by Radio/TV Berlin-Brandenburg for her orchestral composition "Sciciani".

In 2015, she received the German Echo Klassik in the category "Concert Recording of the Year (20th/21st century music)" for playing the Theremin Concerto Eight Seasons by Kalevi Aho, conducted by John Storgårds and played with the Lapland Chamber Orchestra, published in 2014 by BIS records.

In 2016, Carolina began touring her solo Theremin & Voice program. Employing loops and a variety of sound effects, she develops whole choirs onstage and extends the theremin's color palette. By singing without lyrics, voice and theremin often merge symbiotically and can no longer be distinguished from each other.

Her transcription of Ennio Morricone's "The Ecstasy of Gold" got more than 15 million views online. In 2018, she released her single "Reja." Two albums for Theremin & Voice will follow in 2019.

Besides her classical performances and solo concerts, Carolina enjoys collaborating with contemporary artists and has performed or recorded with, among others, rock legend Steve Vai, singer-songwriter Gotye, DJ Jeff Mills, guitarist Jim Moginie, Tangerine Dream, multi-instrumentalist Jacob Collier, and vocalist Theo Bleckman. With electronic musician Eversines she released the album Waves in 2019.

Carolina regularly conducts workshops, lectures, and master classes worldwide. In 2018, she gave a TEDx Talk about the symbiosis of self-control and freedom while playing the theremin. She is the artistic director of the Theremin Academy in Colmar (France), Leipzig, and Berlin (Germany). In her regularly produced instructional videos, Carolina demonstrates her playing technique and theremin basics. Introductions are given in English, German, Arabic, Japanese, Spanish, French and Turkish.
