This bachelor thesis explores the relationship between jazz and harmony from contemporary musical theatre through harmonic transcription and composing new music based on a specific type of harmonic language, to eventually result in a concert performed by jazz musicians.

The study includes the historical differences of jazz and musical harmony, transcriptions of several harmonic movements from different contemporary musicals and my own compositional process. It will also describe the process of rehearsing and arranging the music, resulting in a live concert performed on March 20^th 2023.

 Concludingly, I have found that applying contemporary musical harmony to a jazz setting have resulted in a style of music where the rhythmical approach to the music is amplified due to the simplification of harmonic voices. I also found that it affected the musicians’ rhythmical phrasing into more of a straight eights style of playing.
