Rebetiko was initially associated with the lower and poor classes, but later reached greater general acceptance as the rough edges of its overt subcultural character were softened and polished. Rebetiko probably originated in the music of the larger Greek cities, most of them coastal, in today’s Greece and Asia Minor. Emerged by the 1920s as the urban folk music of Greek society’s outcasts. The earliest Greek rebetiko singers (refugees, drug-users, criminals and itinerants) were scorned by mainstream society. They sang heartrending tales of drug abuse, prison and violence, usually accompanied by the bouzouki.

In 1923, after the population exchange between Greece and Turkey, many ethnic Greeks from Asia Minor fled to Greece as a result of the Greco-Turkish War. They settled in poor neighborhoods in Piraeus, Thessaloniki, and Athens. Many of these immigrants were highly educated, such as songwriter Vangelis Papazoglou, and Panagiotis Toundas, composer and leader of Odeon Records‘ Greek subsidiary, who are traditionally considered as the founders of the Smyrna School of Rebetiko. Another tradition from Smyrna that came along with the Greek refugees was the tekés (τεκές) ‘opium den’, or hashish dens. Groups of men would sit in a circle, smoke hashish from a hookah, and improvise music of various kinds.

With the coming of the Metaxas dictatorship, rebetiko was suppressed due to the uncompromising lyrics. Hashish dens, baglamas and bouzouki were banned, or at least playing in the eastern-style manner and scales.

Some of the earliest legends of Greek music, such as the quartet of Anestis Delias, Markos Vamvakaris, Stratos Payioumtzis and Yiorgos Batis came out of this music scene. Vamvakaris became perhaps the first renowned rebetiko musician after the beginning of his solo career. Other popular rebetiko songwriters and singers of this period (1940s) include: Dimitris Gogos (better known as Bayandéras), Stelios Perpiniadis, Spyros Peristeris, Giannis Papaioannou, and Apostolos Hatzichristos.

The scene was soon popularized further by stars like Vassilis Tsitsanis. His song Συννεφιασμένη Κυριακή – Synnefiasméni Kyriakí became an anthem for the oppressed Greeks when it was composed in 1943 (during the Axis occupation of Greece during World War II), despite the fact that it was not recorded until 1948. He was followed by female singers like Marika Ninou, Ioanna Yiorgakopoulou, and Sotiria Bellou. In 1953, Manolis Chiotis added a fourth pair of strings to the bouzouki, which allowed it to be played as a guitar and set the stage for the future ‘electrification‘ of rebetiko. This final era of rebetiko (mid 1940s–1953) also featured the emergence of night clubs (κέντρα διασκεδάσεως) as a means of popularizing music. By the late 1950s, rebetiko had declined; it only survived in the form of archontorebetiko (αρχοντορεμπέτικο “posh rebetiko”), a refined style of rebetiko that was far more accepted by the upper class than the traditional form of the genre. The mainstream popularity of archontorebetiko paved the way for éntekhno and laïkó. In the 1960s Manolis Chiotis popularized the eight-string bouzouki and set the stage for the future ‘electrification‘ of rebetiko.

Rebetiko in its original form was revived during the Junta of 1967–1974, when the Regime of the Colonels banned it. After the end of the Junta, many revival groups (and solo artists) appeared. The most notable of them include Opisthodromiki Kompania, Rembetiki Kompania, Babis Tsertos, Agathonas Iakovidis and others.

Mikis Theodorakis

Drawing on rebetiko‘s westernization by Tsitsanis and Chiotis, éntekhno (or éntechno) arose in the late 1950s. Éntekhno (lit. meaning ‘art song‘) is orchestral music with elements from Greek folk rhythm and melody; its lyrical themes are often based on the work of famous Greek poets. As opposed to other forms of Greek urban folk music, éntekhno concerts would often take place outside a hall or a night club in the open air. Mikis Theodorakis and Manos Hadjidakis were the most popular early composers of éntekhno song cycles. They were both educated in Classical music and -among other reasons- the lacking of a wide public for this kind of music in Greece, drove them to the invention of Éntekhno, in which they transferred some values of Western art music,[12] such as ballads tune.

Theodorakis was the first composer to use the bouzouki in this genre of music, trying to include this organ into the mainstream culture. Other significant Greek songwriters included Stavros Kouyoumtzis, Manos Loïzos, and Dimos Moutsis. Significant lyricists of this genre are Nikos Gatsos, Manos Eleftheriou and poet Tasos Livaditis. By the 1960s, innovative albums helped éntekhno become close to mainstream, and also led to its appropriation by the film industry for use in soundtracks.

A specific form of éntekhno was the so-called “political song”; songs with political message, of the Left, which arose during the military junta and became very popular after its fall in the late ’70s. Manos Loizos, guitarist Panos Tzavellas, Maria Dimitriadi and Maria Farantouri were some representatives. Thanos Mikroutsikos released an album featuring Greek partisan songs of the Greek resistance, with his own orchestration. A form of éntekhno which is even closer to western classical music was introduced during the late 1970s by Mikroutsikos.
