Vocal Coach

vocals review and feedback


Teaching vocal techniques to over 10,000 individuals, including KPOP stars, actors, and TV personalities.

Hi, my name is Hosi. I've been teaching for over 12 years now

While my approach may not initially seem as entertaining, it prioritizes understanding the actual reasoning and methods behind it. I am committed to helping you feel the difference and will support you every step of the way.

Do you believe that exceptional singers are just naturally talented? Well, I used to be a terrible singer myself. I was the worst in my class when I began attending the vocal academy. The feeling of not being able to achieve what I wanted was overwhelming. However, I was determined to improve my singing skills. I researched vocalization and anatomy extensively, and after a decade, I now teach professionals.

I keep a journal of all the feedback I provide to you and ensure that my students achieve their desired results.

I am now among the top 1% of vocal coaches in Korea. If you want to sing better, I will guide you in the most efficient way possible.

I can't wait to work with you!

Described by the New York Times as “magically atmospheric” and a “vivid capsule of self-expression, often at impressive levels of accomplishment,” his compositions blend the intricacy of art music with the natural flow of jazz and folk music into a seamless whole.

Daniel creates music with a breadth and scope that reflects his unique and distinctive experiences as a Mexican-American composer. Born in El Paso, Texas, Daniel studied composition, conducting, and jazz trumpet at Mannes Conservatory, New School University, and Stephen F. Austin State University. Over the last two decades, he has distinguished himself by engaging in diverse musical idioms.

Daniel’s work in the theatre includes being music director of multiple off-Broadway productions at St. Annes Warehouse and The Kitchen and the famed Experimental Theatre Wing at NYU. He toured Japan several times with Japanese icon Senri Oe as music director, conductor, and arranger.

Daniel’s arrangements for Sting, Plácido Domingo, and Orpheus Chamber Ensemble are a few examples of the sweeping range of his musical vision. His music has been featured at the River to River Festival, Savannah Music Festival, Tokyo Jazz Festival and performed by the Royal Concertgebouw Orchestra, London Symphony Orchestra, and Tokyo Philharmonic. He will be collaborating with the Fresh Squeezed Opera Company in the Summer of 2022, and his album Octubre is set to be released in the Fall of 2023.
