Viola Lessons

Beginners who are at least five years old are encouraged to consider studying the viola. It is the alto voice of the string family and its strings are tuned five pitches lower than those of the violin. Many children find the rich tones of the viola especially appealing. While full-sized violas are larger than violins, smaller sizes are fitted the same as violins for younger students. Violists provide an essential voice in string quartets and orchestras and often are in great demand.

The School has a limited number of violas available on loan for older violin students who wish to add viola skills by playing viola in orchestra or quartets. Occasionally, violin students decide to transfer to the viola; this is an easy adjustment which provides many new opportunities.

The viola program at the Preucil School is highly regarded internationally. Doris Preucil is the author of the "Suzuki Viola School" with William Preucil and Michael Isaac Strauss performing on the accompanying recordings.
