Welcome to Trio Music by Margaret Brentnall

Trio Music has been a centre of music appreciation in the easily accessible neighborhood of Cedarbrae in SW Calgary, Alberta for more than two decades. My studio offers voice, piano, theory and history lessons to students of all ages and backgrounds.


BA in Music with Distinction – Voice major, with a minor in Psychology
Royal Conservatory of Music (RCM) Certified Teacher
RCM Advanced Specialist in both Voice and Theory
RCM Elementary Specialist in Piano

I am passionate about both music and learning. One of my most satisfying sources of learning is through teaching music – my students teach me so much about the learning process!

Although most of my students who participate in exams and festivals receive high marks, I believe the biggest indicator of success is the personal growth that comes in many shapes and sizes for all students. I am open to the different styles of music that pique a student’s interest including popular selections and use of technology.

Motivated by a love of and passion for music, students find me to be a patient, engaging, enthusiastic, and encouraging teacher.

What Students Are Saying

Carmela L

Advanced Theory and History student

Margaret is the best theory teacher I’ve ever had. Whether she’s building a complex chord progression or dissecting the life of a famous composer, she makes theory jump off the page and come alive! When I struggle with ideas she is incredibly patient and encouraging - she has an amazing ability to make complicated concepts easy to understand. Thank you, Margaret, for all your help!
