Book excerpt: Daniels’ Orchestral Music is the gold standard for all orchestral professionals—from conductors, librarians, programmers, students, administrators, and publishers, to even instructors—seeking to research and plan an orchestral program, whether for a single concert or a full season. This sixth edition, celebrating the fiftieth anniversary of the original edition, has the largest increase in entries for a new edition of Orchestral Music: 65% more works (roughly 14,050 total) and 85% more composers (2,202 total) compared to the fifth edition. Composition details are gleaned from personal inspection of scores by orchestral conductors, making it a reliable one-stop resource for repertoire. Users will find all the familiar and useful features of the fifth edition as well as significant updates and corrections. Works are organized alphabetically by composer and title, containing information on duration, instrumentation, date of composition, publication, movements, and special accommodations if any. Individual appendices make it easy to browse works with chorus, solo voices, or solo instruments. Other appendices list orchestral works by instrumentation and duration, as well as works intended for youth concerts. Also included are significant anniversaries of composers, composer groups for thematic programming, a title index, an introduction to Nieweg charts, essential bibliography, internet sources, institutions and organizations, and a directory of publishers necessary for the orchestra professional. This trusted work used around the globe is a must-have for orchestral professionals, whether conductors or orchestra librarians, administrators involved in artistic planning, music students considering orchestral conducting, authors of program notes, publishers and music dealers, and instructors of conducting.
