I have had several opportunities to teach singers in their 70's and 80's. They usually are still singing in a choir and want the mental exercise of continuing to learn. They are often struggling with reduced muscle tone and elasticity, both in their breathing and with their vocal folds, related to aging. In breathing, this shows up when the singer wants to take a full inhale and their diaphragm and rib muscles are slow to respond. With the vocal folds, the reduced elasticity means that the folds no longer stretch for the higher pitches as easily, creating a reduced vocal range.
I have found that a starting conversation around these issues is helpful, as often the older singer thinks they are "doing" something wrong. Most active older adults are already engaged in flexibility and strengthening exercises to maintain their bodies, so they understand immediately the carryover to breathing and singing. We then develop an "exercise plan" for their voice, based on their level of physical well-being, and we transpose songs to approachable keys so they can enjoy their singing immediately.
I have a great time working with this age group. They usually have a great attitude and sense of humor toward their learning process :)
