Dr. Eph Ehly is one of the most sought after choral conductors in the United States today. Ehly has conducted over seventy All-State choirs. However, no previous source outlines the fundamental principles of his philosophy and rehearsal techniques.This study was designed to capsulize Ehly's contributions. The writer produced a videotape entitled, "Eph Ehly: A Source of True Inspiration." This video captures Dr. Ehly's philosophy regarding the All-State choir experience and demonstrates his rehearsal techniques. The author attended three All-State festivals where Ehly was the guest conductor (Indiana, New York, and Oklahoma). The video contains rehearsals and performances and videotaped interviews with Dr. Ehly.The cornerstone of Ehly's approach is this: using music to express. There are three components to Ehly's philosophy: 1) the physical component, 2) the emotional component, and 3) the spiritual component. The writer identified four forms of the physical component: 1) handshake, 2) hug, 3) clapping, and 4) other spontaneous physical gestures. The writer identified eight aspects of the emotional component: 1) expressivity, 2) sensitivity to the world, themselves, and their own emotions, 3) sympathy, 4) reality of emotions, 5) creating mood, 6) building ensemble, 7) music as a reflection of life, and 8) awareness of a "sixth sense." In describing the spiritual component, two divisions were identified: 1) the development of character, and 2) reaching a level of spirit-awareness.The study also summarizes Ehly's rehearsal techniques by outlining his idiosyncratic approach to the treatment of traditional musical elements. The video presentation highlights nine technical concerns and demonstrates Ehly's approach to these common problems. The areas addressed are: 1) tone quality, 2) diction, 3) rhythm, 4) dynamics, 5) phrasing, 6) articulation, 7) breathing, 8) vowel modification, and 9) vibrato. The videotape is supported by a written document containing background information, a script of the video, a summary by the author, a representative list of programs from AllState choirs conducted by Dr. Ehly, and transcripts of the interviews with Dr. Ehly. Church musicians, professional conductors, educators, and students of conducting can all benefit from the opportunity to view and evaluate Ehly's approach. / School of Music
