What does a sharp sign mean in a key signature?

In a key signature, a sharp or flat symbol on a line or space of the staff indicates that the note represented by that line or space is to be played a semitone higher (sharp) or lower (flat) than it would otherwise be played. This applies through the end of the piece or until another key signature is indicated.

How to find the order of sharps in a key?

The order in which sharps or flats appear in key signatures is illustrated in the diagram of the circle of fifths. Starting the major scale pattern (whole step, whole, half, whole, whole, whole, half) on C requires no sharps or flats. Proceeding clockwise in the diagram starts the scale a fifth higher, on G. Starting on G requires one sharp, F ♯, to form a major scale. Starting another fifth higher, on D, requires F ♯ and C ♯. This pattern continues, raising the seventh scale degree of each successive key. As the scales become notated in flats, this is shown by eliminating one of the flats. This is strictly a function of notation—the seventh scale degree is still being raised by a semitone compared to the previous key in the sequence. Going counter-clockwise from C results in lowering the fourth scale degree with each successive key (starting on F requires a B ♭ to form a major scale). Each major key has a relative minor key that shares the same key signature. The relative minor is always a minor third lower than its relative major.

What is the key signature for C major?

Starting on C, this yields C-D-E-F-G-A-B-C (a C-major scale). There are no sharps or flats in this scale, so the key signature for C has no sharps or flats in it. Starting on any other note requires that at least one of these notes be changed (raised or lowered) to preserve the major scale pattern. These raised or lowered notes form the key signature. Starting the pattern on D, for example, yields D-E-F ♯ -G-A-B-C ♯ -D, so the key signature for D major has two sharps—F ♯ and C ♯. Key signatures indicate that this applies to the section of music that follows, showing the reader which key the music is in, and making it unnecessary to apply accidentals to individual notes.

How many sharps are in a major key?

Each major and minor key has an associated key signature, showing up to seven flats or seven sharps, that indicates the notes used in its scale.

When to use naturals in a signature?

Similarly, when a signature with either flats or sharps in it changes to a smaller signature of the same type, strict application of tradition or convention would require that naturals first be used to cancel just those flats or sharps that are being subtracted in the new signature before the new signature itself is written; but, again, more modern usage often dispenses with these naturals.

When does a key signature change from sharps to flats?

In traditional use, when the key signature change goes from sharps to flats or vice versa, the old key signature is cancelled with the appropriate number of naturals before the new one is inserted; but many more recent publications (whether of newer music or newer editions of older music) dispense with the naturals (unless the new key signature is C major) and simply insert the new signature.
