I love all the answers, and this post resonates with a project I started about three summers ago
I offered an adult beginner harp class, and helped those who signed up find rental harps, and wrote a twelve installment healing supplemental approach to adult beginner harp study.
Nobody in the group wanted to stop at the end of the twelve weeks, so we have continued on, and become a truly loving and tight group of people. Throughout the years, they have all experienced great joys and sorrows in their lives, but the common bond of harping has kept them together in a supporting and loving extended family. All of them came to the harp thinking they couldn't learn an instrument, and while there have been struggles to learn certain things, progress has taken second place by far to the joy and healing that they have all experienced by learning to play the harp. And I arrange music so we have multiple parts for all levels, with each part adding something vital to the piece.
Their ages, by the way, range from 55 to 77.
So I heartily agree- never too old!
