Abstract: In this paper, a novel approach is given to evaluate the effect of chorus size on the quality of art music performance using the hesitant bipolar fuzzy multi-criteria decision-making (HBFS-MCDM) framework. The method accounts for positive and negative expert evaluations under conditions of hesitancy concerning five performance criteria: tonal balance, articulation precision, dynamic range, audience cohesion, and emotional expression. To aggregate, expert conductors and musicologists evaluated a hesitant bipolar fuzzy number, and then a weighted decision model was proposed. Results show limited evidence of balanced and consistent performance among all evaluated dimensions across various ensemble sizes. The HBFS-MCDM approach offers a robust and expressive tool for supporting decisions in professional chorals and for actionable insights on ensemble configuration.

Keywords: choral performance evaluation; chorus size; hesitant bipolar fuzzy sets; multi-criteria decision-making; MCDM; art music analysis; subjective judgment modelling.
