Tenor is always viewed as the most difficult part in vocal music, so the tenor is also called “difficult high pitch” in Chinese. The reason for this is that the unwell conception of vocal sounds, the improper way of pronunciation, the blind practice of alto and the fear and nervous state of mind may lead to accidents and faults in tenor performance. The solution is to train, adjust and apply correctly in natural voice districts, vocal organs, resonance organs, voice districts transition, diaphragmatic usage and vocal sound practice. These will be very helpful for vocalists to research, practice and learn singing skills.
