The Compositions series contains published and unpublished scores, sketches, notes, and recordings, of and about Ingolf Dahl's chamber, piano, vocal, and orchestral composition and arrangements. In addition to completed compositions, this series also contains (mostly unidentified) sketches; Dahl's working notebooks; arrangements of works by other composers; and recordings of Dahl's conducting and performance appearances. Recordings of Dahl's own works are grouped with the scores and sketches. All of Dahl's published works are represented (as are some unpublished works). Not represented are Dahl's arrangements of Stravinsky's Danses Concertantes and Petite Suite, and Ives' Third Sonata. All unbracketed titles are Dahl's original folder/envelope titles.
