Theodore (Ted) Mook has survived for over 20 years as a free-lance cellist in New York, Boston and Providence. He has performed concerts, recorded jingles, movie soundtracks, CDs, vinyl albums, DVDs, and appeared on radio, television and even streamed internet content in Europe and the US.

In the commercial realm, he has played in virtually every Broadway show that has a cello, from Phantom to Grey Gardens, opened (and closed) Jekyll and Hyde, Taboo (with the notorious Boy George), Bombay Dreams and Little Women, and backed up performers as diverse as Paul Anka, Juliet Greco, Renee Fleming and JZ.

As an orchestral musician he has performed with the Orchestra of St. Lukes, the American Composer's Orchestra and many others, under the batons of James DePriest, James Levine, Christoph Eschenbach, Dennis Russell Davies, Sir Charles Mackerras and Donald Runnicles, to name a few.

He has served on several Boards for non-profit corporations, negotiated Broadway and orchestra contracts, been a member of advisory committees, produced several commercial recordings, and been the recipient of several prestigious grants and awards.

As a teacher, he has given workshops, clinics, lecture/demonstrations, composer readings and master classes at music schools, colleges and universities across the US and in Europe. He has maintained a private studio for teaching cello, chamber music and solfege almost continuously for the past 30 years.
