You should try to pick up the piano again. You’ll be surprised how much you remember if you go through some beginners books and work up to an easier song. Try going through some of the songs you learned to play on.

kazoo
ocarina
**possibly** harmonica (if you play something very simple, like Mary Had a Little Lamb or Row Row Row Your Boat)

anything else is going to take a lot more than a month to learn.

Try a comb covered with a piece of toilet paper or a Jew’s Harp… any other instrument takes MORE THAN A MONTH to learn.

it depends what area of music your good at
some are better and percussion, brass, woodwwind ect.

but i think the saxaphone is easiest in my expierience
or the recorder

hope this healped

the flute, or tuba.
i play both.
or if you want to get really simple go for the sax!

the flute!!!!!!!!!

i started playing guitar, before i played the recorder, i think u can play anything with the recorder really fast

it’s not the coolest instrument ever, but for our required music class at college, we had to play the recorder… it was not hard to learn at all… worth looking into at least.
