Description
Clarinet multiphonics have become increasingly popular among composers since they were first introduced in the 1950s. However, it is a topic poorly understood by both performers and composers, which sometimes leads to the use of acoustically impossible multiphonics in compositions. Producing multiphonics requires precise manipulations of embouchure force, air pressure, and tongue position. These three factors are invisible to the naked eye during clarinet performance, leading to many conflicting theories about multiphonic production strategies, often based on subjective perception of the performer. This study attempts to observe the latter factor—tongue motion—during multiphonic production in situ using ultrasound. Additionally, a multiphonic catalog containing 604 dyad multiphonics was compiled as part of this study. The author hypothesized that nearly all, if not all, of the multiphonics can be produced using one of four primary production strategies. The four production strategies are: (A) lowering the back of the tongue while sustaining the upper note; (B) raising the back of the tongue while sustaining the upper note; (C) changing the tongue position to that of the lower note while sustaining the upper note; and (D) raising the root of the tongue (a sensation similar to constricting the throat) while sustaining the upper note. To distill production strategies into four primary categories, the author documented his perceived tongue motion over twenty repetitions of playing every multiphonic in the catalog. These perceptions were then confirmed or corrected through ultrasound investigation sessions after every five repetitions. The production strategies detailed in this study are only for finding the correct voicing to produce the multiphonics. The catalog compiled during this study is organized using two different organizational systems: the first uses the traditional method of organizing by pitch; the second uses a fingering-based system to facilitate the ease of finding multiphonics in question, since notated pitches of multiphonics often differ between sources.

Description
This study summarizes survey responses on perceived challenges by conductors who a) identify as female, b) are not citizens of the United States, c) are currently living in the United States, and d) are working in professional positions in the field of orchestral conducting. The goal of the survey was to query the concept of “double minority” (female and non-native to the United States) and to gain insight into the conductors’ self-perceptions and perceived challenges they encounter during their employment and career advancement in the United States.
The survey covered four main areas: educational background, immigration status, the employing orchestra or organization’s budget, and conductors’ challenges and perceptions. Considering the sensitivity of the topic and following best practices of human subjects’ research, participant identities were coded with letters.
Participants expressed more certainty about the issues and challenges concerning how they were perceived as females than as immigrants. There was insufficient data to correlate the budget of the orchestra with the willingness of the institution to be a visa sponsor.
This study’s findings suggest that there are areas that should be further explored such as: the effect a conductor’s nationality has on their career and reception in the United States; how potential motherhood affects the conductors’ careers; organizations’ willingness and ability to hire immigrants, offer sponsorship, and assist the artist in the transition out of the student visa status; and the perceptions and experiences of being an immigrant conductor in the United States.
