Violinist Madeleine Hogue, a native of Fayetteville, Arkansas, is an avid performer, educator, and chamber musician. Her love for diverse musical genres has led her to perform throughout the United States, New Zealand, and Europe. Madeleine holds a Bachelor of Arts in Music from the University of Arkansas, where she studied with Dr. Er-Gene Kahng. She continued her studies at California State University-Northridge, where she earned a Master’s of Music under the tutelage of Dr. Lorenz Gamma. While living in Los Angeles she has cultivated an active role as a chamber and orchestral musician. She served as the first violinist of the Goldberg Honors String Quartet from 2016-2018, where she had the opportunity to work with the Danish String Quartet, Harlem Quartet, Jonah Sirota, Henry Gronnier, Stephen Harrison, and Laura Mcginnis. Madeleine is also a member of the American Youth Symphony and performed as the concertmaster of the California State University-Northridge Symphony from 2016-2018. Music education and community outreach are integral to Madeleine’s musical philosophy. 


In addition to her performance schedule, she works closely with young violinists as a private and group instructor in an effort to give back to the next generation of musicians. Madeleine believes that classical music is strengthened when the voices of marginalized and underperformed composers are given a platform within the genre. She passionately advocates for the study and performance of works that fall outside the traditional repertoire of Western classical music and takes great joy in exploring the compositions of those whom history often elides.
