What is the best (overall) instrument to learn to play at 50 years of age?

I think it comes down to phrasing. You can play a piece with all the right notes and spot-on rhythm and it can still sound bad. Have you done much theory?

Once you understand about all the tendency tones, leading notes, about tension and resolution, that's when the piece turns from punching out notes to sounding like magic. It's like when you see 7 year olds on YouTube playing really hard piece really fast and it looks really impressive, but if you just listen to their playing it sounds nothing at all like a concert pianist playing the same piece. It's about how you express the music, rather than whether your timing and notes are perfect.

I hope that helped a little! All the best with your playing :).

I would have to hear you playing to offer any advice. Do you have any videos on youtube?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
