Margaret Thornhill is an artist/teacher of clarinet in Los Angeles who has performed as a clarinet soloist in the United States and Europe. She made her New York recital debut at Merkin Hall in 1982 and her UK debut at St. Martin-in-the-Fields in 1991.
Critics have raved about her performances of the Mozart Concerto, K. 622 as being "music of incomparable grace and almost unbearable poignance. Thornhill's performance was as loveable as Mozart was loving" (Peninsula Times-Tribune),
of the Stravinsky Three Pieces as "Thornhill's musicality, technique, and control are extraordinary"(Palo Alto Times.)
John Rockwell, former lead music critic of the New York Times, called her performances of Rorem, Brahms, Levy and Berg a recital "nicely planned and nicely played."
On historical clarinets, she has performed and recorded for Centaur records with the Santa Cruz Baroque Festival,
with the Los Angeles Baroque Orchestra at the Getty Museum, and with the chamber groups Divertimento and Clarion.
Margaret was for ten years founder/director and clarinetist with the Matrix Chamber Ensemble, a Los Angeles-based 20th century group which won numerous local, state and national grants and awards,
was selected for the touring roster of the California Arts Council, and performed for Community Concerts.
She collaborates as a chamber musician with Los Angeles Philharmonic, recording studio and LA Opera principals, and is a member of "Category V", a woodwind quintet with oboist David Kossoff, bassoonist John Campbell,hornist Nathan Campbell, and flutist Julie Long. She frequently performs as a duo with pianist Twyla Meyer.
Margaret writes a regular column about clarinet choir literature for THE CLARINET, the journal of the International Clarinet Association, and has contributed articles
on clarinet technique and pedagogy for British Clarinet and Saxophone and Australian Clarinet and Saxophone.

A native of California, Margaret holds degrees from the University of California and Stanford University, where she earned a DMA in performance practice.
Her principal clarinet teacher was the legendary Rosario Mazzeo, with whom she studied for nine years and was his assistant for two. She also studied with Leon Russianoff, of the Juilliard School, with David Breeden, late principal of the San Francisco Symphony,
and historical clarinet Colin Lawson, now head of the Royal College of Music.
