DR. Christine Utomo

Growing up as a student at Irama Music Studio, spent almost a decade in the US to further music study and now back here as the Artistic Director in 2008, I have had the privilege to explore, collaborate, and curate new programs and events: such as Associazione Musicale Amadeus that brought in international artists and performances in Medan; as well as starting licensing with Kindermusik International program and adopting the Suzuki Violin Method; and having selected artists and students to perform at themed concerts, such as "Carnival of the Animals," "Peter and the Wolf, " "Barbar the Elephant," etc. Currently during the COVID-19 pandemic, I am beyond excited to be able to work with my team of dedicated teachers to host weekly Beethoven seminars on Zoom, which has attracted various International artists and professors. 

My goal in teaching is to inspire the mind and heart, and certainly to train fundamental physical strength, especially the ears, fingers, and our body muscles. My hope is that students keep developing curiosity, and certainly skills, critical thinking and understanding of the musical notation in search of the best interpretation that is closest to the composer's original intentions.

Sophie Anggara

Born and raised in Medan, I pursued my Bachelor degree majoring in Classical Piano at UCSI University, Kuala Lumpur, Malaysia under tutelage of Asst. Prof. Dr. Joyce Wang Chiao Su with partial grant scholarship from UCSI Trust. I also took Contemporary Piano as my minor instrument under Mr Adrian Hin Ee Jeng.

During my studies, I was an active participant in joining several competition, workshop, seminars, and masterclasses and exposed to many kinds of music styles & technique as well as musician's well-being. Apart from that, I was given opportunity mentoring students in Aural Skills such as drilling basic hearing skills, giving practice tips and dictation. My interest in other academic subjects also led me to take part as a mentor for Malaysian Music subject. From all those teaching experiences, I truly believe that practical skills, theoretical skills, and hearing skills should be connected altogether without having a gap in between.
