Based upon the work with the chamber opera Ps. Jag kommer snart hem! (Eng. Ps. I will be home soon!), this presentation aims at describing the working process towards a new musical work, as it takes place in the setting of exploratory workshops. Drawing upon observations and conversations, benefits and challenges are brought forward and discussed through the use of examples. An over-arching concept of calibration is presented; the work in focus housed calibration on at least two different levels: calibration towards the work and calibration within the work. As the article concludes, this process is of great artistic value and may also assist in facilitating for the commissioner, and possibly in extension, the presumed audience of a new musical work.
