Not for nothing did Franz Schubert dedicate his last three piano sonatas, culminating achievements in their genre both for him and for the Classical-era piano sonata, to Johann Nepomuk Hummel. The soloist and composer (1778-1837) who had come as a child to Mozart for lessons in Vienna then became a teacher of note in his own right, and an exponent of a fluid, filigree keyboard technique that exercised its own significant influence upon early generations of Romantic composers.

Hummel ‘as a youth … was the most surprising performer that had ever visited [England], except the young Mozart’, reported one English piano manufacturer, and in this absorbing album of his sonatas, the composer’s voice is extended and developed in parallel with that of the instruments he used. We are still a long way from the massive concert grands ubiquitous today when we experience Hummel’s music on the instruments he would have known himself, and this is a uniquely attractive feature of Costantino Mastroprimiano’s interpretations. On this recording he plays a pair of instruments: a fortepiano by Urbano Petroselli, after an original model by Anton Walter ca.1790; and an original Erard ‘en forme de clavecin’ dating from 1838.

The six sonatas on this set range from the Baroque formalities of Op.2 No.3 (suitable for playing on a harpsichord as well as a fortepiano, according to the composer’s superscription) to the four extensive movements of Op.106, with a first movement in particular laid out on a spaciously expressive scale.

This album is a worthy successor to Mastroprimiano’s notable achievement in recording for Brilliant Classics the complete sonatas of Muzio Clementi (now collected in one 18-CD box, 94379), another keyboard pioneer in the early decades of the 19th century. Reviewing volume 1 of the original series, Fanfare magazine reported that ‘With his fluid, brilliant technique and sensitive expression, Mastroprimiano serves Clementi beautifully, as does the excellent sound reproduction.’ Volume 3 was praised in similar terms: ‘Costantino Mastroprimiano plays with crisp accuracy... He wisely doesn’t overplay his hand... This is a fine recording.’
