Key Signatures

You can use accidentals in differant key signatures. Having different key signatures makes music sound more interesting. There are major and minor keys. Most of them are major. For example, there is C major, G major, A major, et al.

The key signatures can be determined by using the "Circle of Fifths." As you go around the circle clockwise, one sharp is added to the staff until there are five sharps. Then, there are six flats and the amount decreases. The key with no accidental is called the key of C. The fifth note, that comes next, is G. This means that the key of G is the key with only one sharp. This is continued throughout the circle. Knowing the different key signatures can be tricky to remember at first, which I still struggle with sometimes, but gets easier over time.
