10BEL MUSIC = Dávid Szedlár
I’m a bass player, producer and songwriter.

Music education & studies
I started my music education at the age of 7 with the piano as my main instrument. I studied at several music institutions in Budapest, Hungary, such as the Bartók Béla Conservatory, the Szent István Király Conservatory, the Kőbánya Music Studio and I graduated from Codarts University in Rotterdam as a bass player and creative producer in 2017. 

Me as a bass player 
In the Hungarian music scene I was a member of popular groups like Unisex, Grover Washington Jr. Tribute Band, UP! and Peet Project. As for international successes, a few milestones are performing at the Seabreeze Jazz Festival in Panama City, Florida and the Catalina Jazz Trax in LA. Currently, I’m playing with Dutch singer-songwriters Lilith Merlot, Marvin Timothy, Sára Hélène, Loren Nine, and the bands ROOKS and The 45.

Me as a producer and songwriter
As for my career as a producer, the very beginnings are connected to my high school years at the sound culture faculty of the Szent István Király Conservatory. I worked for the Hungarian Radio on Music Academy concert recordings and wrote ad music for Paradigma, which were played on commercial radios throughout Hungary. I continued my education as a producer at Codarts where besides my major in bass guitar, I completed a minor in creative producing. I have written and produced film music for Lonely Film, game music for Amaze Escape Events, Escape Room - ss Rotterdam, songs for Hungarian singer-songwriter Boggie and Dutch-Hungarian singer-songwriter Sára Hélène among others.

Me as a teacher
I am also passionate about passing on my knowledge. My main focus in teaching is not only to hand out technical excercises but to help students understand the language of music. I have experience through teaching privately and in music institutions (e.g. Music Soul House Zoetermeer, SKVR Rotterdam, Jay's Place).

The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, often power or intensity. Today, the unit is used for a wide variety of measurements in science and engineering, most prominently in acoustics, electronics, and control theory.
