This document discusses key signatures and how they are constructed based on major and minor scales. It explains that a key signature is a series of tones and semitones determined by whether the scale is major or minor. It provides the formula for the order of tones and semitones in a major scale and uses it to construct the A major scale as an example. It also gives the formula for a natural minor scale and constructs the A minor scale as an example.

A semitone or half step is the movement of sharpening or flattening a note. C > C# C > Cb A tone or whole step consists of two semitone steps. C C > D C > B
Key signatures are constructed using a series of tones and semitones. The order of which are determined by the quality of the scale. For example, whether it is major or minor. A keyboard can help in working out the steps.
The order of these steps for the major scale are: T, T, S, T, T, T, S T = Tone S = Semitone Using that formula to construct A major: A B - C# - D E - F# - G# - A
The order of these steps for the natural minor scale are: T, S, T, T, S, T, T T = Tone S = Semitone Using that formula to construct A minor: A B - C - D E - F - G A There exist other minor scales.
There are three minor scales, natural, harmonic and melodic. The harmonic minor is the same as the natural minor scale except that the seventh degree is raised by a semitone. So, A harmonic minor will be as follows: A B - C - D E - F G# A
For the melodic minor scale, take the natural minor and raise both the sixth degree and seventh degree by a semitone. A melodic minor scale: A B - C - D E F# G# A
