Allen K. Yu

Piano Composer

Allen Kai-Lang Yu

Allen is a classically trained pianist and a life-long composer.

In 2023, after some 30 years of composing privately, he finally created Hidden Harmonies Music to facilitate collaborating with other artists and to promote his music.

Allen firmly believes in music's power to shape, enrich, and transform people's lives and societies.

He has always made music a central part of his life, despite him having pursued careers outside music.

A Big Welcome to Everyone! Allen hopes you will enjoy, stay, and take a life-long journey with him.

Outside earning a B.S., M.S., and D. Engr. degree from UCLA's School of Engineering and a J.D. degree from Harvard Law School, Allen has dedicated most of his life to working in the high tech fields. Allen has deep interests in the sciences, engineering, law, and - of course - music. He lives with his wife and their two homeschooled children in Silicon Valley. The family enjoys walking and hiking with their Husky, caring for their pets (chickens, turtles, and fish), going to junior league bowling tournaments, playing tennis, and golfing.

Holding music in high esteem


Music gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life.


If one should desire to know whether a kingdom is well governed, if its morals are good or bad, the quality of its music will furnish the answer.

Victor Hugo

Music expresses that which cannot be said and on which it is impossible to be silent.

Rabindranath Tagore

Music is the purest form of art.

Albert Einstein

Music is ever-present in the universe, waiting to be discovered. If I were not a physicist, I would want to be a musician.
