Music Sheets


For the past 7 years, Gaby has been an active private and group voice instructor. She has coached students in Chiriquí, Santiago, Coclé and Panama City, Panamá; Boston, Connecticut, in the US, and Valencia, Spain.


Her approach is based on the maxim "every student could learn if have a passionate teacher". In lessons, Gaby incorporates singing and acting, as a fundamental part of the interpretation, transforming a shy student into a strong performer.


Cotter has taught voice lessons to all ages and abilities. The lessons are fun and are personalized for each student.  The lessons are taught in a non-competitive, nurturing environment.


Lessons can take place in her Boston, MA studio or Online

Gaby taught me to believe in my sound as an interpreter. She also helped me to improve my guitar skills. Now I feel ten times more confident performing. She encourages me to do the repertoire I love and nailed it.

I learned with Gaby, to love my voice, the uniqueness sound I have, and how finding a repertoire needs to be adapted to me and not the opposite. Now, every time I'm on the stage, I feel way more comfortable and start to enjoy the rush of the audience.

Gaby gave me the confidence I was looking for in a teacher. 
Her mantra of focusing on the process and keep trying, helped me to achieve my goals.
