The Sunnah is to recite the Qur’an at a measured pace, not quickly or hastily. It should be read in a manner that clearly distinguishes each letter, beautifying the Qur’an with one’s voice. You should observe the well known rulings of reciting the Qur'an (known in Arabic as the science of tajweed).
It is the sunnah to recite the Qur’aan in a beautiful melodic tone, but one should not recite it in the innovated manner of singers or according to the rules of music (i.e. melodic modes), as Muḥammad ibn Seereen (may Allah have mercy on him) said:
