Ebrahim Hamedi is a singer. He is nicknamed as “Mr. Voice” . He achieved the pinnacle of his fame and success towards the end of the 1970s.

A singer is someone who vocalizes musical sounds with tone and pitch, and uses his or her own voice to produce music. Singers may sing solo or in a group, and are oftentimes accompanied by instrumental music. The physical act of singing occurs as air passes through the larynx, throat, and mouth, and it’s interesting to note that vocal resonation in singing involves seven areas of the human body: chest, tracheal tree, larynx, pharynx, oral cavity, nasal cavity, and the sinuses.
