Stewart Yu

Hi, I'm Stewart!

I write music, play piano, and sing. Musical theatre and pop.

Fun fact: I'm also a web developer.

What I Do


With over 2 million views and some viral hits, I've been building a following on YouTube with my quirky videos over the past few years.


Story telling through music makes any story richer. Crafting just the write words and sound is key to a successful musical.

Music Directing

I music direct/conduct musical theatre, and write vocal arrangements. I also help actors prepare for their singing auditions.


Singing is what got me hooked on theatre. I've been known to act and play piano onstage too.
