At the core of ACMS are weekly Saturday afternoon coachings with members of the Artaria String Quartet. These sessions teach students the techniques and artistry needed to interpret important Classical, Romantic, and Modern Era chamber music masterpieces. Artaria nurtures individual responsibility to the preparation of each piece, supportive group dynamics, and diplomacy. 

Trimester masterclasses with Artaria and acclaimed guest artists offer all ACMS students opportunities for first performances of works-in-progress and advice for further development.

Community outreach performance opportunities are provided throughout the school year as well as regional and national competitions. ACMS groups have been invited to appear on Minnesota Public Radio and APM's “From the Top”, and are national prizewinners of the Saint Paul String Quartet Competition. ​​
