...ARE CAPABLE OF TALKING AND SINGING WITH STRONG, VIBRANT VOICES! (assuming there is no impairment from disease, injury, or disorder, of course)
Popular mythconceptions about older adult voices are: (1) their pitch and volume ranges will diminish, (2) clarity of vocal sound will diminish, and (3) a wobbly vibrato happens when singing...because of aging processes.
'Tis true that there will be some changes in the muscles and other tissues of the larynx due to progressive aging, BUT...nearly all the changes in older adult vocal capabilities that are blamed on aging, are not the result of aging at all!
They are the result of deconditioning and reduced efficiency in the neuromuscular coordinations that produce vocal sound (particularly in the internal muscles and other tissues of the larynx).
Read, now, about Olga Johnson, pictured above, who has lived on planet Earth for 82 years, who dearly loves to sing, and has been studying singing with Leon since the early 1990s.
