the style taught at the Great Church of Constantinople, which is more elaborate and is practised in parish churches. Nowadays the Orthodox churches maintain chanting schools in which new cantors are trained. Each diocese employs a protopsaltes ("first cantor"), who directs the diocesan cathedral choir and supervises musical education and performance. The protopsaltes of the Patriarchates are given the title Archon Protopsaltes ("Lord First Cantor"), a title also conferred as an honorific to distinguished cantors and scholars of Byzantine music. Ioannis Arvanitis While Angelopoulos' school basically stuck to the transcriptions of Chourmouzios the Archivist who did transcribe as one of the great teachers also the Byzantine repertoire according to the New Method during the beginning of the 19th century, another student of Karas Ioannis Arvanitis developed an autonomous approach which allowed him to study the older sources written in Middle Byzantine notation. Ioannis Arvanitis published his ideas in several essays and in a doctoral thesis. He founded several ensembles like Aghiopolitis which performed the tradition of the Byzantine cathedral rite based on his own study of medieval kontakaria and asmatika in Italy, or got involved in collaborations with other ensembles whose singers were instructed by him, such as Cappella Romana directed by Alexander Lingas, Ensemble Romeiko directed by Yorgos Bilalis or Vesna Sara Peno who studied with Ioannis Arvanitis, before the she founded an own Ensemble dedicated Saint Kassia and to the Old Church Slavonic repertoire according to the Serbian tradition of the Athonite Hilandar Monastery.
