The science of Tajweed is the midpoint between the Koranic and linguistic studies. It is recommended to the post-graduation and graduation students who are working in those two fields to have a strong interest in the art of Tajweed , in order to reform their tongues to utter both of the Holy Koran verses and the Arabic text correctly and eloquently whatever the type is , discourse ( prose or poetry) , fiction or parable The research is based on three principals converging together in the uttering method of the Arabic letter. I wrote it , benefited from those who mastered this field, to contribute in preserving the letters of revelation from the sounds of intruders who don’t know the rules of Tajweed , and to participate in purifying the Arabic tongue, taming it to utter correctly and eloquently and to mend its vocal path to be up to the standard of the Arabic language which is merited by Allah and his worshipers.
For this purpose , I made the following research , entitling it by “Adjusting the Tongue and Correcting its Vocal Path through through the Science of Tajweed ”, with four main titles , introduction and conclusion including the important results obtained.
The titles are : the definition of the science of Tajweed and its inception, the relation between the sciences of Tajweed and recitation modes, the ranks of recitation and its effect on the uttering, the articulation of sounds and its features and effect on the voice.
