Human voice is unique and different from others, and its damaging impact onus all. To recognize the vocal difficulties it is necessary to have the knowlegde of anatomy and physiology of the vocal apparatus, vocal hygiene and education. Vocal difficulties restrict, prevent, reduce the vocal ability of vocal professionals. Causes of vocal difficulties of teachers are central, functional, organic and psychogenic. Singing is one of the most frequently performed activities in Music teaching and therefore the students of different vocal ability, maturity of voice, color and volume, diversity of repertoire, weight content and other issues are exposed to vocal difficulties. With the help of optical and acoustic analysis of voice usage we will eliminate vocal difficulties of students. Music teachers voices are not excluded from vocal problems. Hoarseness or dysphonia is main liquidity indicator of the existence of vocal difficulties. The big challenge for Music teachers is to note and know to remove the vocal difficulties of students. During my study, especially at singing classes as a part of the main subject at the Departnent of Solo Singing, I dedicated great attention to my vocal techniques, the study of voice, the impact of vocal difficulties on the voice and the elimination of vocal difficulties. Therefore, this work is focused on the vocal difficulties in teaching Music and necessity of knowledge of the vocal hygiene.
