We’re Committed to Your Satisfaction


OTA Music Studio Director

Katherine Dalin (Known to her students as Miss Kat) has been teaching privately throughout the greater Chicagoland area since 2008. She holds degrees in voice performance, theatre, and pedagogy and is a member of  the National Association of Teachers of Singing, the Somatic Voice Teachers Association, and the American Guild of Musical Artists. Ever adding tools to her teaching toolkit, Ms. Dalin recently trained in the Lovetri Somatic Voicework method, a teaching method geared specifically towards developing students of Contemporary Commercial Music-a broad banner including many non-classical vocal styles (Musical theatre, folk, rock, etc).

Her primary instrument is voice and she is a teacher who practices what she preaches, performing musical theatre, cabaret, straight theatre, operetta, and opera.  Praised for her onstage “exuberance” and “memorable” portrayals as well as her energetic and quick-witted sense of comedy, Katherine Dalin lights up the stage with her rich, luminous contralto voice and charismatic stage portrayals. 

Her secondary instruments include: piano, violin and, the most recent addition in 2020: ukelele.

She works regularly with youth theatre companies both as a director and music director and also has the great privilege to teach early childhood music classes at several local preschools.
