About William

William Kim is a professional vocal coach who has worked with artists and trainees from major Korean record labels including YG Entertainment, CUBE Entertainment, and MNH Entertainment. He specializes in both vocal training and artist development, helping singers build a reliable, healthy voice while also developing the skills and mindset needed to work professionally in the industry. His coaching focuses on efficiency, consistency, and real-world application. William has trained extensively in Speech Level Singing (SLS), studying in Los Angeles since 2013 under Maestro Seth Riggs through private lessons and workshops. He integrates the core principles of SLS with modern K-pop and Western pop styling to help singers develop a natural, powerful, and sustainable voice.

About the lesson

Many people may think that singing and music do not have rules; you may even want to be creative and unique and break the rules. However, if you want to sing well, understanding the scientific principles of human anatomy is helpful. If you want to produce the exact same pitch visualised in your head, you need to first learn how to control the corresponding muscles. While singers who are naturally gifted can do this easily without thinking, most other singers can also achieve it with the correct training and practice.

  Cause and effect pedagogy based on Speech Level Singing technique is taught during lessons. It is a technique adopted by over 130 Grammy awards winners, and it is now spread globally. Many popular contemporary singers such as Michael Jackson, Stevie Wonder, Michael Bolton, Natalie Cole, Barbra Streisand, Madonna, and many more  took singing lessons with the founder of the SLS technique, Seth Riggs.

Perfect! William is a great voice teacher, he was able to put my daughter at ease straightaway and pinpointing what she needed to focus on or change to improve her singing. He is very patient and able to explain the reason for focusing on certain techniques or exercises so that she understood why she needed to sing in certain ways.

Perfect! Amazing first session! This is the first time I've tried vocal lessons so I was a bit nervous but all the nerves went away less than a minute into the session. William was very friendly. He explained everything really clearly and broke things down in a way that was easy to follow. I felt comfortable throughout the lesson and learned a lot in a short time.

Perfect! William is an excellent vocal teacher who is able to quickly identify and correct singing problems. I had no idea I was singing incorrectly until I took a lesson with him. He was able to pinpoint my problems and provide me with specific exercises to fix them. I am confident that with his guidance, I will be able to improve my singing a lot.

I also appreciated William's positive and encouraging teaching style. He made me feel comfortable and confident, even though I was a beginner. He was always patient and willing to answer my questions.

I would highly recommend William to anyone who is serious about improving their singing. He is a knowledgeable and experienced teacher who can help you reach your goals!

Perfect! Two lessons so far - Knowledgeable about the voice, including relevant anatomy! Genuinely listened to my concerns and incorporated them into lessons. Tailors exercises to my capacity and learning needs. Also, just really kind and accommodating (I slept in and missed half the lesson today) and easy to talk to. Overall, very encouraging teaching style and has a lot of professional expertise to offer!

I have been working with William for 4 lessons now as a compete beginner.

William is a very knowledgeable and friendly vocal coach who focuses on the sound and anatomy of the voice rather than just doing textbook vocal exercises, resulting in a more tailored and effective learning environment.

I’d recommend William whether you’re serious about getting better at singing or just doing it as a hobby as he is more than qualified to address all your issues regarding singing.
