The Izel Band brings together Grade 8 students currently studying at SenTia School. The name "Izel" symbolizes uniqueness and freshness, reflecting the musical style the band aims to share with their audience. Currently, the band consists of one vocalist, two guitarists, one pianist, and one drummer.

What makes The Izel particularly special and a source of pride is that all their covers are collaboratively arranged and performed entirely by the band members. Recently, The Izel has had the opportunity to perform at events such as Gió Đầu Mùa and the EU Christmas Fair at the Czech Embassy. Notably, the band was honored to win the Bronze Award in the Band category at the Gió Đầu Mùa 2023 competition.

Founded in the first semester of the 2023–2024 academic year, Trà Đá is the creation of eight talented girls from Grades 6–7 at SenTia School, united by their shared passion for music, particularly the gentle acoustic genre. Despite their simplicity and modesty, the members of Trà Đá always leave a lasting impression, much like the refreshing essence of a glass of iced tea.

In the past semester, Trà Đá was honored to represent SenTia School with their voices and instruments at various events, including the Christmas Village at the Marriot Hotel and the EU Christmas Fair at the Czech Embassy.

The name "Groovania" is a combination of "Groove" and "Mania." "Groove" refers to grooving—being immersed and moving to the rhythm of the music, while "Mania" signifies a passionate enthusiasm for something. "Groovania" embodies the spirit of living life to the fullest through music.

Established in September 2023, Groovania comprises 10 artists, two managers, and seven backstage members.

Glee – Groovania was founded to create a space for talented young individuals who love music and aspire to shine while doing what they enjoy. Beyond performing, the band serves as a platform for learning and sharing musical experiences and knowledge, igniting and sustaining each member's passion for music.

In the first semester, Groovania engaged in a variety of exciting activities, including SenTia Street Music, a podcast series, art workshops, Gió Đầu Mùa, and the Xmas Concert.
