Stella's Secret Sonata Music Folio 2

In his will, composer Dudley Donegal O’Day left his entire library (including originals of his finished and unfinished orchestral works) to the University of Vermont. While cataloguing O’Day’s collection in January 2022, University of Vermont volunteer music historian Mirabella Reid discovered, stuffed inside many pages of 'The Life of Mendelssohn' by Peter Mercer-Taylor, an unpublished and previously unaccounted for sonata. On folded yellowing paper, the undated work is titled ‘Violin Sonata’ and is dedicated ‘To Stella’. Research has revealed no links or mentions of the work as it was being composed (or later), or to Stella, though the work contains many of the composer’s musical signatures. There is no question as to its authorship: the sonata is definitely Dudley Donegal O’Day’s own work. There are three movements to O’Day’s sonata: Allegro, Adagietto, and Molto Allegro. No one knows who Stella is ... so, who was (or is) Stella? So the question is ... are the accounts of 38 writers detailing just who Stella is, telling the truth?
