Five Notes in a Bach Theme

Fifty leading language models were each asked, in isolation, to write a piano melody of five notes in a Bach theme. Their replies are rendered here as they might appear in a Baroque manuscript collection — each incipit on its own staff, each model a copyist.

❧ Editor’s Note ❧

Of the 41 models that returned a melody, 38 yielded five parseable note-names sufficient to place on the staff; 3 required the marginalia treatment. The corpus reveals a powerful gravitational pull toward C major: 13 responses named it explicitly, against 8 citing D minor as the next most frequent key. The most common opening note is C (15 of 38 melodies), and across all five positions the five most-used letter-names are D, G, C, E, F — a near-exact match for the C major pentatonic scale. The single most recurrent five-note pattern is C–E–D–G–C, chosen independently by 2 models. Rather than exploring the Baroque idiom’s full chromatic and modal range, the models converge: ascending scalar runs and simple arpeggiations of the C major triad dominate, suggesting their training associations with “Bach” route overwhelmingly through the same pedagogical C-major canon.
