it is difficult to image this wonderful score more exquisitely played or radiantly engineered.

This is developing into a delightful series – Vol 3 sees Alina Ibragimova and Cédric Tiberghien find immense charm and character in these sonatas from across Mozart’s life. Tiberghien and Ibragimova come close to my ideal Mozartian duo, in performances that further whet the appetite for the rest of the series.

They don’t patronise the 10-year-old’s works — the allegro of No 16 (B flat major) sparkles in their mercurial hands — but they reserve their finest playing for No 23 (D major) and Mozart’s last sonata for this combination in F, No 36.

once again it is hard to imagine a better partnership. Each of the six works in this double CD programme is a pure delight, with exquisite playing from these world-class performers – Ibragimova fleet and lithe, Tiberghien playfully delicate.

Ibragimova introducing some playful interpolations into the Allegro of K31. Both players skilfully characterise its tempo di menuetto variations. Ibragimova adding subtleties of nuance and rubato and occasionally taking some of the limelight. Her silky-toned, lyrical playing in the expressive central movement of K306 is an aural delight, and both protagonists revel in the humour, drama and sheer invention of the ensuing operatic finale.
