Singer-songwriter Younha has returned with the seventh full-length album, GROWTH THEORY, after almost three years since the release of her sixth album, END THEORY. This album is not only the second part of the THEORY album trilogy but also released as part of her twentieth debut anniversary promotions and celebration.

“It’s the second work of the THEORY trilogy, and I believe this would be the biggest in terms of depth out of the whole series. I hope this album can support those who are sailing each life’s journey while maintaining their values and dreams.” - Younha

Continuing the narrative in END THEORY, GROWTH THEORY tells the meaning of growth that a girl learns by connecting with various subjects along her mighty journey. The first five tracks of the album, “맹그로브 (Mangrove tree),” “죽음의 나선 (Antmill),” “케이프 혼 (Attention!),” “은화 (Silvering),” and “로켓방정식의 저주 (Curse for the rocket formula),” describe the fear of a mysterious world and the courage to break that fear. The sixth and title track of the album, “태양물고기 (Sunfish),” is a rock track that conveys the message that it is correct to walk on the path you truly believe in, no matter what others think or say. Then the last four tracks, “코리올리 힘 (Coriolis force),” “라이프리뷰 (Life review),” “구름의 그림자 (Part of cloud),” and “새녘바람 (East wind),” narrate the discovery of dynamic emotions, experiences, and courage at the end of the journey as a new person. 

Throughout the album, multiple instruments such as electric guitar, accordion, Irish whistle, Janggu (Korean drums), and Kkwaenggwari (Korean small cymbals) were incorporated to accentuate unique sounds and vibes in each track. Younha participated in the composition and lyrics of all 10 tracks in the album.
