The 3 hour introductory course offers a theoretical run-through of Complete Vocal Technique. I will present and demonstrate technique and theory, using the extensive collection of illustrative CVT charts and, of course, practical vocal examples. All participants will participate in exercises: The very basis of the course is that all theory has to be practically applicable and is always illustrated by practical examples (10am to 1pm).

After lunch break, a masterclass (2pm to 5pm) offers individual counseling for the singers, with the other participants as an audience – a great learning experience for both active singers and listeners. A professional piano player will be present for accompaniment. Complete Vocal Technique works in all styles of music, so all genres and styles are welcome – classical, musical theater, folk, pop, R&B, soul, rock, etc. 

Fee for the 1-day-seminar & master class in the SF East Bay is $130,00 per participant.

The participants are asked to bring a song, or parts of a song, containing vocal technical difficulties to be worked on during the master class. Please bring sheet music for the course pianist. There is a free app containing basic knowledge of CVT (you will find "CVT app" in the App Store or Google Play); participants are encouraged to browse through the app in preparation of the course, but it's not required. 

More Course Info

There is room for 8 active singers at each introductory course. Minimum number of participants is 5. Minimum age limit is 17. The course is laid out as group instruction. We'll make sure to create an environment of openness and trust, so that everyone feels comfortable. The participants will share and benefit from the different learning experiences of the other singers, especially in the master class. The goal is an intense and effective working process that will allow the participants to use the newly acquired skills immediately after the course. CVT is all about teaching the singers how to do it by themselves.

Please note that this course serves as an audition for the programs at the Complete Vocal Institute in Copenhagen. Please go to for more info. All participants will receive a certificate upon completion of the course. 

About the Course Content

Singing is not that difficult and everybody can learn to sing. Catherine Sadolin, founder of CVT, has created a method that is based on four main subjects, as listed below. By combining elements of these four subjects, you can produce precisely the sounds you want. You will also be able to pinpoint your specific problems and mistakes and find concrete tools to handle and eventually eliminate them.

The four main subjects in CVT are:

  1. The three overall principles – to ensure healthy sound production.

  2. The four vocal modes – to choose the ‘gear’ you want to sing in.

  3. Sound colors – to make the sound lighter or darker.

  4. Effects – to achieve specific sound effects.
