A Sunday concert [graphic].

"Musicians are grouped round a piano. Their names (some misspelled) are written in the margin. The pianist sits in profile to the right looking fixedly at his score; he is Ferdinando Bertoni, a Venetian composer who accompanied his friend Pacchierotti to England. The most prominent of the musicians is Pacchierotti, who stands behind the piano next the pianist, holding open a music book, but smiling at a lady, who sits (right) on a bench among the performers. She is Lady Mary Duncan, whose admiration for Pacchierotti's singing was the talk of the town, carried to the point of absurdity, and of discourtesy to other singers. (Walpole, 'Letters', xii. 141, 3 Jan. 1782, and xv. 16-17, 4 July 1791.) She is the largest figure in the design, out of scale with the other figures. She sits in profile to the right holding up a closed fan, gazing intently at Pacchierotti. Behind her stands the player of the bass, identified as Cariboldi. Seated on the bench next her, on her right hand and wearing spectacles, is a man playing the oboe, identified as Hayford. Seated in a chair in front of Lady Mary and on the pianist's right hand is the cellist, Cervetto, evidently the younger Cervetto (1747-1837), who played at the professional concerts at the Hanover Square Rooms from 1780. Behind the piano stand (left to right) a violinist, identified as Salpietro, an oboist, J. C. Fischer (1733-1800), who was a great attraction at the Bach-Abel and Vauxhall concerts, and another violinist, Langani or Langoni. To the right of the piano, blowing the French horn, stands Pieltain. In the foreground (right) in profile to the left sits Miss Wilkes on a stool, her hands in a muff, smiling at Dr. Burney, who stands bending towards her, his hands held out. He wears a bag-wig and sword, and appears to be deep in conversation in spite of the singing of Pacchierotti, a fashionable habit much condemned by his daughter Frances, see 'Cecilia'. Behind Miss Wilkes on the right stands another of the audience, holding his hat under his arm."--British Museum online catalogue
