William - Get to know your vocal coach
I am a professionally trained tenor and singing teacher with postgraduate training from the Guildhall School of Music & Drama in London. As an active performer, I have experience in opera, classical song, pop, musical theaters and I enjoy bringing the practical knowledge I have gained from professional training, rehearsals, performances and masterclasses into my teaching. My lessons are tailored to each student because I believe every voice develops differently. I work with students on wide range of age, from kids to adults alike. Rather than simply asking students to imitate a particular sound, I want them to be able to develop their own voice and sounds with confidence. I welcome beginners as well as more experienced singers. If you are completely new to singing, I can help you build strong foundations and confidence step by step. My teaching style is encouraging, patient and detailed, but also practical. I like to create a relaxed environment where students feel comfortable experimenting, making mistakes and discovering what their voice can do. I understand that singing can sometimes feel very personal and vulnerable, so my aim is to give students clear tools they can use independently. Most importantly, I want students to enjoy singing. Whether your goal is to sing for pleasure, improve your confidence, prepare for an audition, develop your classical technique or simply understand your voice better, I will adapt our lessons to your individual goals and help you progress at a pace that works for you.

Singing concepts taught by William
The session covered foundational singing techniques, including the Tutor's holistic approach to vocal support, diaphragm breathing, and proper posture. The Student practiced vocal scales to explore both high and low ranges, focusing on chest resonance and smooth transitions between vocal registers. They also discussed and demonstrated how to avoid vocal strain and began applying techniques to a song, with plans for ongoing warm-ups and song work.
