>>2045579have you considered trying the mouth organ? a simple ten hole diatonic harmonica is easy and small to carry, best of all they are fairly water resistant! (they are constantly filled with your spittle). the layout of the notes is pretty easy to pick up, if you hold your tongue against the holes at the front and blow out and breath in through the side of your mouth you can make little melodies and stuff. great fun. my grandpa was a captain on the ships and always carried one to play a tune or two when there was a moment of downtime. also its a good way to learn proper breathing techniques, we all could benefit from breathing a bit deeper
