How wud u define a sharp, flat, and natural notes? {music}?

Question

I play the clairinet

Answer 1

Sharp: a sign indicating that the pitch of a note
should be raised by a semitone.

Flat: a sign showing that a note should be lowered
by one semitone.

Natural: a sign that, after a particular note has been
raised by a sharp or lowered by a flat, restores it to its
original pitch.

Bonus:
Semitone: normally, the smallest notated pitch
difference in Western music-for instance, G to G
sharp.

Answer 2

You could define it in terms of the piano. A sharp is a half step up from a natural note. A flat is a half step down from a natural note. (usually the black keys on the piano). Natural notes are the white keys on the piano.
