Italy's rough geography and the historic dominance of small city states has allowed quite diverse musical styles to coexist in close proximity.
Today, Italy's folk music is often divided into several spheres of geographic influence, a classification system proposed by Alan Lomax in 1956[1] and often repeated since.
In the 1950s, a number of important field recordings were conducted by American Alan Lomax and Italians Diego Carpitella, Franco Coggiola, Roberto Leydi among others.
Toward the end of the decade, a special effort was made to capture the folk traditions of the Meridione (southern Italy), including an important study by Carpitella and anthropologist Ernesto de Martino of the tarantella.
The NCI was an assemblage of musicians and composers including Giovanna Marini that made its first major public appearance at the 1964 Spoleto Festival dei Due Mondi and generated a large number of records and concerts.
[3] Roots revivalists have revived traditional songs, though, from Piedmont (La Ciapa Rusa, Tre Martelli), Lombardy (Barabàn, Pandemonio) and Veneto (Calicanto).
The highly urban provinces of northern and central Italy are also known for the medieval sung poetry ottava rima, especially in Tuscany, Lazio and Abruzzo.
Ottava rima is performed by the poeti contadini (peasant poets) who use the poems of Homer or Dante, as well as more modern lyrics which address political or social issues.
Probably the most culturally distinct of all the regions in Italy, Sardinia is a Mediterranean island known for the cantu a tenore polyphonic chant, sacred songs called gozos, and launeddas, a woodwind instrument similar to the Greek aulos.
The ottava, or eight-line stanza, is a common lyrical form in Sardinia, one which allows the performer a certain amount of improvisation and is not unlike the stornello of south-central mainland Italy.
In November 2005, the Cantu a Tenore vocal style of the Sardinian pastoral culture was proclaimed a Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO.
Other influential Sardinian musicians include Totore Chessa (organetto), Maria Carta (singer), Mauro Palmas, Elena Ledda and Suonofficina, Cordas et Cannas, Paolo Fresu (trumpet), Gesuino Deiana (guitar), Tazenda, Marisa Sannia.
