Greek Orthodox Chanting is a traditional form of vocal music used in the Greek Orthodox Church. It is characterized by its unaccompanied melodies, which are often based on ancient Byzantine musical scales. The chanting is typically performed during religious services, enhancing the spiritual atmosphere and helping to convey the meaning of the texts. The chants are usually sung in Koine Greek or Modern Greek and include various styles, such as hymns and psalms. This practice has deep historical roots, dating back to the early Christian church, and continues to be an essential part of Orthodox Christian worship today.
