Scope and arrangement
The Louis Horst Course Materials and Research collection consists of copied sheet music and notes used by Horst to conduct his classes at Juilliard, as well as research materials on Louis Horst compiled by Janet Mansfield Soares.
The course materials consist primarily of copied music used in lecture and dance classes. This includes Horst's original compositions for classroom activity, as well as his adaptations of the works of others and commercial sheet music. There are often notes in the margins of the music. Accompanying these documents are two roll books for Horst's Juilliard classes, one of which is begun by Horst and completed by Soares, who took over his courses immediately after his death. The teaching materials also hold a set of music and instructions from a course Horst taught in the 1930s entitled Body Power. There is no indication as to the institution at which this course was offered. These materials include copies of original Horst compositions as well as a detailed list of what exercises were to be performed to what music. The Body Power materials were donated independently of the Soares gift.
Music holds two examples of published Horst sheet compositions. These are his work for Martha Graham's El Penitente and his Rhythmic Design, which includes diagrams of the Perry-Mansfield exercises.
The research materials are composed of genealogical research, photocopied articles, and transcripts of interviews collected by Soares in the course of researching her book Louis Horst: A Musician in a Dancer's World. The bulk of the material is photocopied.
