Sharps, Flats and Naturals
At this point, it’s time to turn your attention to the rest of the notes on the piano and music score that we have not yet covered; sharps, flats and naturals. Quite simply, these represent the black notes on the piano. Whenever a sharp appears on the piece of music, you must play the note one semi-tone above. Similarly, whenever a flat appears on the piece of music, you must play the note one semi-tone below (see the diagram below).
Sharps and flats can appear in music score in two forms. Sometimes they appear next to the note and sometimes they appear as part of the key signature.
Whenever a sharp/flat appears next to a note, that note should be played as a sharp/flat for the remainder of that bar.
Alternatively, the sharp/flat will appear in the key signature. This means that every time these notes appear at any point throughout to piece of music, you will need to play the sharp/flat shown in the key signature.
Should a natural sign appear at any point throughout the piece; this will cancel out the sharp/flat that has previously appeared. These examples should make everything clearer.
