Research Summary (1) Taking advantage of the distances and synergies of some instrumental and lyrical musical compositions to improve "Solvian Singing" Music is one of the most important arts related to the sense of hearing, and hearing training is a basis on which musical sciences are built and provides the specialized student with theoretical information, And practical exercises that are used to develop his musical abilities, Based on the researcher's teaching of the subject "hearing training" for the second year of the BA stage, I found it difficult for many students in distinguishing between the harmonic distances, Its singing was like a melodic space and I found it most difficult to construct the melodic distance from the different vocal degrees, This leads to their poor performance in singing Alsulfaie, Therefore, the researcher thought about making use of some well-known music heard by students, analysing and using them to strengthen the performance of distances and melodic and harmonic combinations, singing and building them to improve their performance in solvian singing. The research included (problem - objectives - importance - hypotheses - research limits - sample - tools - approach - terminology). The research followed the experimental method (one group). The research is divided into two parts: The theoretical part includes • Previous studies related to the research topic • The theoretical concepts of research namely : Solfege - the importance of hearing training for a music student, whatever his specialization - items of western solfege - rhythmic Solfege - melodic Solfege - the concept of Solfege singing – distances . Application part: It includes • Procedural steps for research • Analyse music tracks.
