|The viola d'amore is a special interest of Rachel Barton Pine's.|
For the most part, the accompaniments are for string orchestra with harpsichord (David Schrader), but a particularly fascinating piece is the Concerto in F major, RV 97, with the resonant string instrument partnered with horns and oboes, plus (in the slow second movement), a bassoon.
The viola d'amore, which gave way to the viola we know today, enjoyed a vogue in the Baroque era because its equal number of bowed and resonating strings (totaling 12) gave it a warm aura as a solo instrument that could hold its own in the ensembles of the day. And this is how Pine plays it, fully engaged with the Chicago-based period-instrument ensemble.
Vivaldi achieved a great deal of variety in his settings for the instrument. Sometimes a stately theme
To close out the set, there is the late concerto, again in D minor (RV 540) that brings in the lute as a secondary solo instrument. Hopkinson Smith is Pine's partner for it, which is notable for a refreshing exchange of phrases between lute and viola d'amore in the finale.
