Abolhasan Saba, Esmaeil Ghahremani and Ali-Naqi Vaziri were among his students. Mírzá 'Abdu'lláh was one of the most influential masters of Persian classical music. Because of his desire to collect and assemble a large repertoire of traditional pieces, and because of his generosity of spirit, and his willingness to teach others, the particular rendition of Persian music he collected has become the most widely known and the most practiced among contemporary Persian musicians.[1]
