She was considered a paramount principal soprano in English oratorios or other works of the sort by Handel and by other composers. Frasi was at nine consecutive meetings of the Three Choirs Festival: she sang for William Boyce at Hereford in 1756, then she performed for Arne, and so on. She gave regular concerts in Oxford too. She also continued to be part of the Covent Garden oratorio concerts given by Handel and, later, by John Christopher Smith and John Stanley. (The latter two would produce their own oratorios (or other works suitable for the occasion) whilst also putting together revivals of Handel's.) In fact, after Handel's death in 1759, Frasi continued as Prima Donna under his successors until about 1768. In total Frasi also participated in at least fourteen opera seasons at the King's Theatre between 1742 and 1761. In addition to which, during the 1754-1756 seasons, Giulia regularly covered for Regina Mingotti. (Mingotti's fits of temper, antagonisms with the director of the opera
