The Preparatory Orchestra directed by Kris Yenney (PACO ’74) further explores and develops fundamentals introduced in the SuperStrings ensemble. More challenging orchestral and ensemble repertoire is prepared for public performances through which the budding young artists further refine the process of creating chamber music together.  One Winter concert and one Spring concert highlight the season, featuring orchestral and chamber works and live program notes presented by the musicians. Opportunities to perform community service at local venues supplement the season and add the important value of community service to each PACO member’s participation. More accomplished players are given leadership and solo parts and, with the occasional addition of wind and brass players, allow Preparatory Orchestra to perform a broad and varied repertoire.

Kris Yenney, Director of the SuperStrings and Preparatory orchestras, is also currently Director of Orchestras at the Woodside Priory School in Portola Valley and of a community chamber choir, the M'EarthTones. An accomplished cellist, Kris began her studies in Palo Alto before going East to earn a BFA from SUNY Purchase and a M.M. from the New England Conservatory of Music. Inducted into "Who's Who in American Colleges and Universities," Kris was also honored as the first woman to win the John W. Work Composers' competition for her original work, "Jabberwocky," both in 1985. Having joined the Palo Alto Chamber Orchestra in 1967, Kris has been involved with the organization ever since, as active member, soloist, camp counselor, coach, guest soloist, workshop faculty and director. Many of her private cello students have joined the ranks of PACO over the years. Invited by William Whitson in 1999 to direct the SuperStrings, she took the helm of the Preparatory group in 2002 and also directs one of the three Bach Celebration Concerts each Spring.

Kris has performed in several professional chamber ensembles over the years. As cellist of the New England String Quartet, she participated in festivals and competitions worldwide and was Artist-in-Residence for UMass, Boston and Amherst. A founding member of the Left Coast Ensemble and of the Palo Alto Sunrise String Quartet, she currently performs and records extensively on the cello, viola da gamba and voice in the Celtic/Early Music quartet, Broceliande.
