Is it possible to start or resume practicing an instrument at any age?
But yes of course !
Music requires concentration and mastery at the physical and intellectual level.
It makes our brains work a bit, it is true that depending on the way you work and play it can quickly become athletic.
Some works are very physical and we can also injure ourselves and cause cramps and tendonitis if we take bad habits, bad positions or if we work too long sessions!
A bit like the athlete who would run a hundred meters without warming up !!
So, it will be important even if one has already practiced the instrument to do it in a certain progression.
Do not cut corners. In no time you will find your marks and the pleasure of replaying your old songs!
Moreover for those who are interested in posture and kinesiology, I recommend going for a walk on the website of Médecine des Arts and this concerns all instrumentalists as well as pianists as strings, winds, brass or percussion.
But it is obvious that you can start or start again at any age and why not do it like this grandmother student of a 7-year-old girl who took the opportunity to get back to it when her little girl wanted to start the instrument, what better than to be able to play together one day !!
There are many pieces for beginners with 4 hands, the repertoire is so rich that it wouldn't take a lifetime to play them all.
