2torial #0917: Learn2 Read Music Understand key signatures Natural notes appear by themselves in written music. But sharps and flats have their own symbols: Sharp Flat On a keyboard, a sharp note is the black key that's one note higher than its natural counterpart (the white key). A flat is a black key that's one note lower than its natural counterpart. When sharps and flats are written into music as needed (next to the notes), they're called accidentals. But sometimes they are shown at the beginning of a stave, right after the clef. In this case, they indicate a key signature. Key signatures show which notes are to be played or sung as sharps or flats throughout the song. So if there's a sharp sign on "F" and one on "C", every "F" and "C" note throughout the song should be played as a sharp. There will be no "F" or "C" natural unless specifically indicated by a natural symbol: Natural Key signatures (in this case, D Major) indicate the general tone of a song, as well as where its basic scale begins and ends. For example, a song in the key of D is based on the D Major scale, which begins and ends with "D" -- with "F" and "C" played sharp throughout. However, the same song can be written and played in different keys. Step 7
