Colleen Kobussen - Piano, Voice

Classically trained but a lover of all styles of music, Colleen began teaching piano lessons to children and adults almost 20 years ago. After graduating summa cum laude from UC Berkeley, she became one of the top professional piano accompanists in San Francisco, Salzburg, and eventually New York City, where she accompanied for voice studios at Mannes College of Music and the Juilliard School. In New York, Colleen worked extensively as the studio pianist for the late Claire Alexander. Ms. Alexander was the voice teacher to many successful singers, such as Sinatra, Clooney, Belafonte, and others. Working at that studio crystallized Colleen's understanding of the principles and mechanics of the human voice, and over time, Ms. Alexander began referring voice students to her. As a vocal coach, Colleen can impart the warm-ups from the studios of world-class teachers; help with the fundamentals of intonation, enunciation, and phrasing; inventing great arrangements catered to you, your voice, and your style! We are glad she's part of the team at KGMC.
