Giovanni Armonio Marso (–), called Johannes Harmonius Marsus in Latin, was an Italian Renaissance humanist, friar, playwright, poet and organist.
Armonio was born in the Marsica, probably at Tagliacozzo, between 1475 and 1480. His cognomen, Marso, refers to his place of origin. By 1500, he was living in Venice, when Pietro Bembo wrote to Andrea Gabrieli inviting him to bring Armonio to his villa in Padua. He was already then known as a poet. It is not known when he joined the Crutched Friars (Crociferi) or when he joined the Cappella Marciana under . He was living in the church of Santa Maria Assunta dei Crociferi at least from 1506.
In 1516, Armonio became the first or second organist of the Cappella. In 1530, his stipend was raised from 60 to 80 ducats. Including Christmas and Easter bonuses, he would have made 120 ducats a year. According to, he founded a musical academy in Venice with Antonio Molino around 1530. On 22 November 1552, he was replaced by Annibale Padovano and given an annual pension of 70 ducats. The date of his death is unknown.
Armonio wrote drama in Latin. His signature work is his five-act comedy Stephanium, which he wrote and first performed in the church of Santo Stefano in Venice at an unknown date. The play was successful, being praised by Marcantonio Sabellico for reviving Roman theatre. An undated edition was printed at Venice under the title Ioannis Harmonii Marsi comoedia Stephanium urbis venetae genio publice recitata.[1] It contains further praise from and Lelio Gregorio Giraldi. Armonio also wrote a five-act tragedy, De rebus Italicis deque triumpho Ludovici XII regis Francorum tragoedia, about the Italian campaign of King Louis XII of France, probably around the same time he wrote the Stephanium. It was not as well received and is preserved only in a single manuscript from France. Both of his plays have received modern editions.[2]
Armonio also wrote Latin poetry. In 1502, one of his poems was set to music and sung by at a reception for Anne of Foix-Candale, then passing through Venice on her way to marry King Vladislaus II of Hungary. Gabrieli included the text in his account of the event, Libellus hospitalis munificentiae Venetorum in excipienda Anna regina Hungariae. Some of Armonio's poetry was also included in the second volume of Lodovico Domenichi's Rime diverse di molti eccellentissimi autori, printed at Venice in 1548.[3]
If Armonio wrote any music during his 36 years as a professional organist, it has not survived.
