If you mean counting triplets as in how to write them then you write them as you would any normal triplet. A quaver triplet would be a crotchet and a crotchet triplet would be a minim (although crotchet triplets aren't used much)
This answer is honestly completely opinionated. For me, I think music is the closest thing we have to mind control. It can make you happy when you aren’t, or vice versa. It can make you do inexplicable dance moves that are just lovely. But this is a question completely up to you.
The flute, drums, and and clavicord to name a few.
