{"value"=>"<p>The scores are divided into chamber music, operas, orchestral music, piano music, vocal music and arrangements of music by other composers. Most of the scores are unbound ink or pencil manuscripts (bound scores are noted as such); occasionally there are printed scores, but almost none are published. Most of the scores have opus numbers on them; opus numbers for scores without them are derived from a biographical pamphlet in the collection (in Box 23, Folder 4). Some scores have opus numbers which do not match up to the list on that pamphlet.</p> <p>The largest portion of the scores consists of Block’s eight operas. Each of them has at least the libretto and full orchestral and piano-vocal scores. Two, <span class=\"title\">Rauschgold</span> and <span class=\"title\">Samum</span>, have orchestral parts as well. Block’s chamber music includes string quartets, piano quartets and quintets, and sonatas for violin, oboe, clarinet and alto saxophone, among other works. The scores for the chamber music usually contain parts as well as full scores. His orchestral music includes four symphonies and several pieces for string orchestra or chamber orchestra. The piano works include a bound collection of early pieces (1927-1932), nocturnes, marches, a few works for four-handed piano and several untitled/unidentified pieces. Block’s vocal music consists primarily of songs and lieder for voice and piano, but also includes <span class=\"title\">Five Folksongs For Chorus</span> and three works for voice and orchestra. Block’s arrangements of other composers’ music include a version of Tchaikovsky’s <span class=\"title\">Dance Of The Sugar Plum Fairy</span> for four clarinets and transcription of Mahler’s incomplete <span class=\"title\">Symphony No. 10</span> for piano, four hands. This series also contains untitled sketches and orphan score pages.</p>"}
