Martha Marie Petri


Martha Marie Petri (b. 1989) is a Danish cellist with a multifaceted musical mind and background. As a child she received dance, flute, singing and piano lessons, but her first encounter with the cello wasn’t until the age of 16. Despite her relatively late start with the cello, Martha has engaged in many contexts, both as a cellist and cello teacher. She seeks out cutting-edge musical genres and techniques to constantly improve herself, both as a performer and instructor. Martha lives in Aarhus, Denmark, where she has resumed her conservatory studies as a graduate student specializing in contemporary music after a stay in Chicago (USA). Apart from her studies at The Royal Academy of Music in Aarhus, she trains to become a Suzuki teacher, works at Aarhus Music School, sings in the Aarhus Cathedral Choir at Aarhus Domkirke, and plays concerts both in Denmark and internationally (most recently in Carnegie Hall). 

Martha is the driving force behind new projects like the Aarhus-based Ensemble Edge (, and she works as a coordinator/fundraiser for the new cello festival AARHUS CELLO EXPO(


ENSEMBLE EDGE is the first Aarhus-based chamber choir entirely dedicated to performing contemporary music (with strings). The choir is made up of a selection of the best classical choral singers in Aarhus (European Capital of Culture, 2017).
