Emmerich Kálmán (1882-1953) was a leading composer during the Silver Age of Viennese operetta. His final work, Arizona Lady (1954), premiered posthumously, on Bavarian Radio, January 1, 1954. The stage premiere followed on February 14, 1954, at the Stadttheater in Bern, Switzerland. It is his only operetta that is set entirely in the United States, in Tucson, Arizona. Arizona Opera commissioned and produced a new adaptation of Arizona Lady, which was performed in October 2015, in both Tucson, Arizona, and Phoenix, Arizona. The libretto was heavily revised, as well as translated, primarily into English with some sections in Spanish and German.

Through comparison of the original and adaptation, this study examines the artistic decisions regarding which materials, both musical and dramatic, were kept, removed, or added, as well as the rationale behind those decisions. The changes reflect differences between an Arizonan audience in 2015 and the European audience of the early 1950s. These differences include ideas of geographical identity from a native versus a foreign perspective; tolerance for nationalistic or racial stereotypes; cultural norms for gender and multiculturalism; and cultural or political agendas. Comparisons are made using the published piano/vocal score for the original version, the unpublished piano/vocal score for the adaptation, archival performance video of the Arizona Opera performance, and the compact disc recording of the 1954 radio broadcast premiere.

The trained singer utilizes an awareness of her body as an instrument. When she becomes pregnant, her body changes in numerous ways to support the pregnancy. Many of these changes have great impact on her ability to sing during the pregnancy and postpartum periods. The voice may be altered positively or negatively by the release of hormones. The body undergoes many changes that affect the posture and breathing required for singing. Most notably, the abdominal muscles are greatly impacted by the pregnancy. They are stretched by the growing uterus, and this affects their function. In addition, the linea alba (the connective tissue between the halves of the rectus abdominis) is softened by hormonal increases and subject to stretching as the uterus grows, predisposing it to weakness. Since the other abdominal muscles attach to the linea alba via connective tissue, maintaining the integrity of the linea alba during pregnancy and postpartum is vital to the operational function of the abdominal muscles. Protecting the vulnerable linea alba must be deliberately undertaken in two parts. First, conscious exercise is needed to preserve the linea alba during pregnancy and to rehabilitate it after pregnancy. Targeted exercises strengthen the transverse abdominis and shorten and approximate the two halves of the rectus abdominis. Second, modifications in daily movement are necessary to protect the linea alba while performing routine activities. Cesarean sections present additional surgical concerns for singers, including abdominal incisions, use of medication, and the rare need for general anesthesia via intubation. Recovery from a cesarean can be difficult due to abdominal pain, yet steps may be taken to speed healing at the hospital and at home. This paper provides an overview of how pregnancy affects the singer, discusses the effects of pregnancy and cesarean section, and provides a plan to protect the abdominal muscles during pregnancy and rehabilitate them in the postpartum period. It combines information from the fields of physical therapy, medicine, and surgery into a guide for the singer and voice teacher.

The teaching of singing remained remarkably stable until, at the end of the twentieth century, advances in the understanding of voice science stimulated dramatic changes in approach to vocal pedagogy. Previously, the technology needed to accurately measure physiologic change within the larynx and breath-support musculature during the process of singing simply did not exist. Any prior application of scientific study to the voice was based primarily upon auditory evaluation, rather than objective data accumulation and assessment. After a centuries-long history, within a span of twenty years, vocal pedagogy evolved from an approach solely derived from subjective, auditory evidence to an application grounded in scientific data. By means of analysis of significant publications by Richard Miller, Robert Sataloff, and Ingo Titze, as well as articles from The Journal of Singing and The Journal of Voice, I establish a baseline of scientific knowledge and pedagogic practice ca. 1980. Analysis and comparison of a timeline of advancement in scientific insight and the discussion of science in pedagogical texts, 1980-2000, reveal the extent to which voice teachers have dramatically changed their method of instruction. I posit that voice pedagogy has undergone a fundamental change, from telling the student only what to do, via auditory demonstration and visual imagery, to validating with scientific data how and why students should change their vocal approach. The consequence of this dramatic pedagogic evolution has produced singers who comprehend more fully the science of their art.
