Is a piano a transposing instrument?

Question

i really need to know cause so plz tell me

Answer 1

No. Piano music is played at the same pitch as it is written.

A standard guitar is a transposing instrument, as the music sounds an octave lower than it is written. Descant and sopranino recorders play an octave higher than the music is written.

There is a long list of transposing instruments starting about 2/3 of the way down this Wikipedia page:

For most of them the transposition is more complex than changing the octave.
