Bach and other baroque composers. This study investigates the formal function of stretto using a corpus analysis of Bach’s use of stretto in the forty-eight fugues of the Well-Tempered Clavier. It documents details regarding each instance of stretto within the corpus and explores connections between these data using graphs and statistical tests, generally as well as in investigation of three specific hypotheses. The conclusion, density, and quantity hypotheses predict that there will be more stretto passages, time-intervals between onsets of adjacent entries in stretto passages will become smaller, and there will be more entries per stretto passage towards the end of the composition.
