Pietro Nardini (April 12, 1722 – May 7, 1793) was an Italian composer and violinist.
He was born in Fibiana and studied music at Livorno, later becoming a pupil of Giuseppe Tartini. Having been a student of Giuseppe Tartini, he moved to Germany where he joined the court chapel in Stuttgart where he became conductor in 1762. However, he abandoned his duties in Württemberg in 1765 to become Kapellmeister, in 1770, to the Grand Duke of Tuscany in Florence.
As a violinist, he earned the admiration of Leopold Mozart. Nardini is mentioned in Hester Lynch Piozzi's Observations and Reflections Made in the Course of a Journey Through France, Italy, and Germany (1789) as playing a solo at a concert Mrs Piozzi and her husband, Gabriele Piozzi, gave in Florence in July 1785.
As a violinist, Nardini wrote a few compositions, though not numerous. Each is melodious and highly playable, useful in technical studies. Best known are the Sonata in D major and the Concerto in E minor.
As friend of Leopold Mozart, he witnessed the arrival of Wolfgang Amadeus Mozart on his first visit to Italy and his attempts to find a sustainable position in 1770-1771. He also met the bohemian composer Václav Pichl, Kapellmeister to the Archduke Ferdinand d'Este, Austrian governor of Lombardy.
Of his playing, Leopold Mozart, himself an eminent violinist, writes:
"The beauty, purity and equality of his tone, and the tastefulness of his cantabile playing, cannot be surpassed; but he does not execute great difficulties." His compositions are marked by vivacity, grace, and sweet sentimentality, but he has neither the depth of feeling, the grand pathos, nor the concentrated energy of his master Tartini.
