Abstract: As an important part of vocal music training, “humming” has been paid more and more attention to by vocalists and vocal music lovers. Correct humming practice can relax the throat, beautify the voice, control the breath and protect the voice. It can help the practitioners to find the correct singing state as soon as possible, and obtain good breath support and resonance effect, so as to produce a high pitched and beautifulsound with good head cavity resonance.
