Gabriele Leone (born Naples c. 1735 â 1790) was an Italian musician and composer who lived in Paris during the middle and later part of the 18th century. A virtuoso on the violin and mandolin, he wrote an early mandolin method, Analytical method for mastering the violin or the mandolin in 1768 and composed for both instruments. He was an early teacher of the duo method, an advanced technique which would reappear in the 20th century, taught by Giuseppe Pettine in the United States.
In the 1700s, the mandolin spread across Europe for the first time, through performances by masters of the instrument. Leone was one of those early masters who spread the mandolin in Europe, giving concerts and teaching. He spent time in London (1762âÂÂ1763) as director of the London Opera before returning to Paris where he performed at the Concert Spirituel from 1760 to 1766. One of his students was Louis Philippe II, Duke of Orléans, the father of King Louis Philippe I (the last French king).
He referred to himself on the covers of his works as M<sup>r</sup> Leone de Naple (Monsieur Leone of Naples).
His mandolin method was meant to help students of the violin switch to the mandolin, "from bow to feather" without the need for a teacher, using sheet music marked with "conventional signs" to guide learners. Feathers were used as plectrums in that era, as they had been when playing the mandore. The method contained 26 dancing tunes, 6 minuets, 2 duos, a sonata and some airs.
