Mashadi Isi became a connoisseur of classical Eastern, especially Azerbaijani mughams, and taught his knowledge and artistic skills to the young singers of the "Khanandalar majlisi". He performed "Rast", "Shur", "Humayun", especially "Mahur" dastgah with a unique individuality. Along with ghazals and poems of Azerbaijani poets, he also sang the works of Hafez and Saadi Shirazi. According to musicologist Jalil Baghdadbeyov, Mashadi Isi was the first to sing the poems of Azerbaijani poets in gatherings.[2]
