Barbad (باربد; late 6th – early 7th century CE) was a Persian poet-musician, lutenist, music theorist and composer of Sasanian music. He served as chief minstrel-poet under the Shahanshah Khosrow II (590-628). A barbat player, he was the most distinguished Persian musician of his time and is regarded among the major figures in the history of Persian music.
Despite scarce biographical information, Barbad's historicity is generally secure. He was highly regarded in the court of Khosrow, and interacted with other musicians, such as Sarkash. Although he is traditionally credited with numerous innovations in Persian music theory and practice, the attributions remain tentative since they are ascribed centuries after his death. While none of Barbad's music or poetry is fully extant, a single poem survives, as do the title of some of his compositions.
No Sasanian sources discuss Barbad, suggesting his reputation was preserved through oral tradition, until at least the earliest written account by the poet Khaled ibn Fayyaz ( () 718). Barbad appears frequently in later Persian literature, most famously in Ferdowsi's Shahnameh. The content and abundance of such references demonstrate his unique influence, inspiring musicians such as Ishaq al-Mawsili. Often described as the "founder of Persian music", Barbad remains a celebrated figure in modern-day Iran, Afghanistan and Tajikistan.
Posthumous sources refer to the Sasanian musician with little consistency. Persian sources record "Barbād" while Arabic scholars use Fahl(a)bad, Bahl(a)bad, Fahl(a)wad, Fahr(a)bad, Bahr(a)bad and Bārbad/ḏ. Modern sources most often use "Barbad", a spelling that Danish orientalist Arthur Christensen first asserted to be correct. However, the German orientalist Theodor Nöldeke suggested that spellings from Arabic commentators such as "Fahl(a)bad" were really an arabicization of his actual name, probably Pahrbad/Pahlbad. Nöldeke furthered that "Bārbad" was a mistake in the interpretation of ambiguous Pahlavi characters.
