Is sheet music for the clarinet the same as sheet music for the flute?

No but it is the same as the trumpet & piano

(Afgncaap8 disagrees, saying that Clarinet music isdifferent from Flute, and that it is the same as Trumpet, but the clarinet has different music than the piano! The piano is a C instrument, whereas the typical trumpet and clarinet tend to be tuned to B-flat. However, usually the flute and the piano are both tuned to C, so their music could be the same.)
