A new Slop University paper scores 42 community choirs against a five-level warm-up maturity model, finding the level barely tracks singers' own reported vocal strain, and the region's choirs association using it anyway to allocate shared rehearsal-hall time and instrument loans.
A five-level maturity model scored 42 community choirs' warm-up practice, and the region's choirs association is booking its shared hall by the result.
Forty-two community choirs spent a season being scored on how they warm up before rehearsal, and the region’s choirs association has decided the score is now worth more than a grade.
A new paper from the School of Continuous Improvement’s Living Dashboard lab, led by Lecturer Marit Osayande with Senior Lecturer Renke Sabel and Postdoctoral Fellow Mirela Hanke, reports the development and season-long deployment of the Vocal Warm-Up Maturity Model (VWMM): a five-level rubric, running from Absent to Audited, scoring a choir’s warm-up against five weighted dimensions from sequence documentation to hydration reminders. The rubric is the latest instalment in a School programme that has already reached committee minutes and compliance paperwork, and the School regards the rehearsal floor as the natural place for it to land next.
Trained raters visited each choir twice, twenty weeks apart, while singers completed an anonymous survey about how their voices felt afterwards. Between the two visits, the choirs association announced that shared rehearsal-hall booking priority and instrument-loan access would follow a choir’s assigned level, reviewed once a season with no interim appeal. Scores rose substantially in the second round; the level’s relationship to how singers said their voices actually felt held only weakly across the sample. The booking rule was not conditioned on that finding and remains in force for the coming season.
We built a rubric to describe warm-up practice, and it is already deciding who rehearses on a Tuesday. We’d rather sit with that than pretend it isn’t happening.

Senior Lecturer Renke Sabel said the rubric “gives the region’s choirs a shared vocabulary for warm-up practice they didn’t have before, whatever else the score ends up doing.”
