Instruments I have played at varying levels of proficiency over the years:
Bagpipes, Trumpet, Guitar, Bass Guitar, Synthesizer, Harmonica, Tin Whistle.
The only one I was ever really good at was the bagpipes, but that was mostly down to the 10,000 hours thing. I practised them a lot for a number of years.
I have played guitar and trumpet fairly recently but have pretty much decided that I prefer to listen to the experts so mine are left in peace right now.
I still think there is a certain mental health benefit from playing music though, so nowadays when I feel the need I pick up a tin whistle and play a little tune or two.
