This treatise is a selective annotated bibliography of transcriptions for the solo clarinet alone and solo clarinet with piano. The purpose of the document is to demonstrate the significance and importance of transcriptions and justify their inclusion in the canon of solo clarinet literature. This is accomplished by an introduction outlining the general scholarly study of the history and direction of transcriptions and their application to the clarinet repertoire, the main body of annotated bibliographical entries for 156 transcriptions for solo clarinet and clarinet with piano, and a conclusion that includes three groups of data organized by composer, transcriber, and original instrumentation. The selection process for each entry involved the following criteria: the transcription must be an exact (or close to exact) replica of the original with minimal modification, it must be technically idiomatic enough so that the technique does not overshadow the musical intent, it must be a published work in the classical genre, intended for performance by accomplished clarinetists, and the transcription must form a complete and convincing musical entity. Each entry includes the composerís name and brief biographical information, title of the composition, name of the transcriber/s, publisher information (publisher, location, and date), instrumentation of the transcription and original music, level of difficulty, and the length of the score and/or clarinet part. Additional comments are made regarding the history, technique, modifications to the original score (if any), and any other pertinent information that would give the reader a more thorough understanding of the piece. The bibliography can be used for performance, research, and pedagogical purposes. It is organized by historical period with data at the end of the treatise organized by composer, transcriber, and original instrumentation. The quantity and quality of the transcriptions included are the chief factors which justify the inclusion of these works in clarinet repertoire publications, performances, and pedagogy.
