Sir Paolo Tosti (April 9, 1846 – December 2, 1916) was an Italian, later British, composer and music teacher.
Tosti is remembered for his light, expressive songs, which are characterized by natural, singable melodies and sweet sentimentality. He is also known for his editions of Italian folk songs entitled “Canti popolari Abruzzesi”.
His most famous works are Serenata (lyrics: Cesareo), Good-bye! (lyrics: George J. Whyte-Melville) which is sometimes performed in Italian as Addio (lyrics: Rizzelli), and the popular Neapolitan song, Marechiare, the lyrics of which are by the prominent Neapolitan dialect poet, Salvatore Di Giacomo. Malia, Ancora and Non t’amo piu were and remain popular concert pieces.
