William Shield’s early career as a violinist and violist took him to the centre of musical life in London where he became principal violinist of the Covent Garden theatre orchestra in 1773. The publication of the Violin Duets later that decade marked the launch of Shield’s success as a hugely popular composer. Each set of duets is neatly engineered, with many attractive details in the Italianate spirit of Op. 1. The Op. 2 set is more compact, developing arioso vocal styles, clever changes of texture, and folk elements such as hurdy-gurdy-like figurations.

It was Prince Nikolaus of Esterházy’s increasing infatuation with the baryton that compelled Haydn, the prince’s Kapellmeister, to write an unprecedented body of 125 works for baryton trio. The instrument is more like a viola d’amore than a bass viol and has extra strings behind the neck that provide resonance and opportunities for plucking effects. The six works in this album are intimate expressions of great beauty with a sustained level of invention, all of which reflect the prince’s increasing confidence in the instrument.
