The purpose of the lecture was to investigate the historical and musical heritage of the Moravian Church, with a particular interest in the works and players of the American Moravian Trombone Choir. The historical overview of people, customs, and practices is traced from its beginnings with the Unitas Fratrum in Bohemia through the Northern Germany settlement of Herrenhut and the establishment of the American Moravian colony at Bethlehem, Pennsylvania. The musical life of the church is represented by a discussion of the early hymns of the founding fathers in Bohemia and the subsequent instrumental music of the Moravian trombone choir in America. The trombone choir played chorales that were used to call the congregation to order, announce important visitors to the town, and provide music at special occasions. Anthems were played by trombones (when players were available) in regular church services, or outside when it was necessary to double voice parts. Concerted music was played in the Bethlehem Collegium Musicum. Biographies of the players of the 18th and 19th century trombone choirs provide information attesting to the proficiency and dedication of these musicians. A list of players who contributed to the trombone choir movement since the 19th century is included, …

The study described through content analysis the general music course in the secondary school as perceived in selected curricular sources from the 1960's and 1970's. As various writers of curricular sources developed their own content and methodologies, a vast amount of data became available which seemed unmanageable because of the particular philosophical goals chosen for the course. The study organized in a systematic manner the content and methodologies of the.course by means of eighteen categories. Categories of high frequency inclusion in the general music sources were shown to be the elements of music, music vocabulary as a specific area for learning, the predominant choice of classical Western/art music, the use of listening and creative activities and the discussion of psychological learning principles.

The specific problems investigated involved identifying and describing the characteristics of fundamental frequency, overall intensity, and spectral content in unaccompanied and ensemble performance settings. Additionally, comparisons and descriptions of the relationships among these acoustical parameters were made. Fifteen trombonists were used as research subjects. Each subject recorded a selected musical excerpt in the following performance modes: high register unaccompanied, harmonic, and unison ensemble; and low register unaccompanied and unison ensemble. Tape recordings of these subjects were used in conjunction with certain electronic apparatus to obtain data on frequency, intensity, and spectral content. Based on these data, descriptions of these acoustical parameters and comparisons of unaccompanied and ensemble performance settings were made.
