{"value"=>"<p>The scores are in two divisions: those for Frenkel's compositions and arrangements, and those for music by other composers. Some are in fragile condition.</p> <p>Frenkel's compositions number around 50, and include works for solo violin, violin/piano sonatas and concerti, string quartets, works for solo instrument or voice with string orchestra, pieces for various combinations of strings, and violin studies. There are several untitled works which bear written identification numbers (as opposed to opus numbers). These numbers seem to have been assigned posthumously by Frenkel's son. A few untitled works have no numbers assigned, and there are several folders of untitled and unfinished sketches.</p> <p>Frenkel's arrangements are usually for either solo violin or violin and piano. They include music by Kurt Weill (a published version of Sieben Stücke nach der \"Dreigroschenoper\" for violin and piano), Mozart, Beethoven, Brahms, Mozart, Vivaldi, Paganini, Handel, Jerzy Fitelberg, Karol Rathaus and Heinze Teissen.</p> <p>Scores by other composers are for violin concerti and sonatas, solo violin, string quartet, or arrangements of other works for violin. Most of the scores contain Frenkel's bowings and other performance notes; some are signed by the composers with dedicatory notes to Frenkel. In addition to standard repertoire figures (Bach, Beethoven, Brahms, Chopin, Handel, Mahler, Paganini, Ravel) the composers include Frenkel's contemporaries. These include Ferruccio Busoni, Paul Dessau, Jerzy Fitelberg, Rudolph Goehr, Berthold Goldschmidt, Paul Hindemith, Bronislaw Huberman, Frederick Jacobi, Philipp Jarnach, Alexander Jemnitz, Henry Jolles, Friedrich E. Koch, Nikolai Lopatnikoff, Marcel Mihalovich, Karol Rathaus, Max Reger, Max Schillings, Artur Schnabel, Karol Szymanowski, Alexandre Tansman, Heinz Tiessen, Ernst Toch, Stefan Wolpe, Kurt Weill, Henri Wieniawski, and Pantscho Wladigeroff. Composers with the most content are Fitelberg, Goehr, Mihalovici, Rathaus, Reger, Szymanowski and Tansman.</p> <p>Most of these scores are published, but a few are in manuscript form, and may have been gifts from the composers. Composers with manuscript scores include Kurt Weill (the violin part and a published version of his Violin Concerto, Op. 12, both with Frenkel's notes), Paul Dessau, Jerzy Fitelberg, Rudolph Goehr, Berthold Goldschmidt, Karol Rathaus and Alexandre Tansman. The single Beethoven score is his Romanze for Violin, in a manuscript written by the 19th century violinist and composer Ferdinand David.</p>"}
