In keeping with the spirit of Mozart’s flexible instrumentation options for these concerti, we have chosen a small ensemble for this recording: six violins, two violas, one cello, and one bass.
The piano used is a fortepiano built by Paul Downie, Auckland-based harpsichord and fortepiano maker, after models by Anton Walter, circa 1800. It was tuned in unequal temperament at A430. The instrument has the usual knee lever for the period; the left lever is the moderator, and the right is the damper lift. Paul Downie had been building keyboard instruments based on historical models and restoring early keyboard instruments in Auckland since 1978.
