For over three quarters of a century the Polychordia String Library has enjoyed a reputation as one of the finest string collections in existence for school and training orchestras.

From the primary grade collections of Baroque dances to such advanced grade work as Vaughan Williams' Charterhouse Suite, the Polychordia String Library carefully takes the string orchestra from its very beginning problems to a stage of concert performance proficiency.

Every aspect of string performance is surveyed - from the open string pieces of the primary books to the detailed articulation and bowings of the middle and upper grade collections. But it is the music itself which has won so many fine teachers to Polychordia. 17th and 18th Century dances by Couperin, Lully, Arne, and Purcell; sontata movements by Vivaldi, Albrechtsberger, and Boyce; instrumental excerpts from the Bach cantatas, the Handel oratorios, and the Purcell operas; sinfoniettas of Mozart and Haydn - the Polychoridia Library is a treasury of repertoire unmatched in its excellent taste and in the painstaking editing that has gone into the series by James and Sebastian Brown.

The Library is written for a string orchestra of Violins (I & II), Violas, Cellos and Basses, and Piano, and is divided into five progressive grades: Primary, Lower, Middle, Higher, and Advanced. The Piano part is not graded and serves a dual role as a support and, at times, as an independent obbligato. In most of the music the Piano can be used or omitted at the conductor's discretion, and one of the beauties of the Polychordia Library is its flexibility; almost any grouping can be utilized. For example, if violas and celli are weak or missing, the music can be performed with Violins I & II and Piano.
