Piano notes question?

Question

If in the middle of a piece of music, you see a sharp or flat symbol next to a note, does that make the rest of the notes in that measure a sharp or flat unless noted with the natural symbol? Or does that only happen when the key signature is noted at the very beginning of the piece.

Answer 1

It means the note by itself is sharp/flat only. The piece would have to be noted at the beginning.

Answer 2

absolutly right!

Answer 3

For the rest of the measure, that note is sharp. For example after an F#, all of the rest of the F's are F#'s.

A piece ALWAYS has a key signature If there is nothing there, than it is in C major (or it's relative minor, A minor) and everything is natural.

Answer 4

You are correct... It is called an Accidental and it does make the rest of the notes in that measure sharp or flat.  Good for you :))
