If you know the minor scale, the root of the relative major is always the third note of the minor scale. For example, “F” is the third note of the D minor scale (D, E, F, G, A, Bb, C). F major is the relative major of D minor. It works the same for all minor scales.
There are two types of tonalities (or keys) in tonal music: major and minor. The accidentals--sharps and flats--most used in keys are standard so they are often written as key signatures to avoid cluttering the music score with too many accidental signs.
The most used graph for visualizing the relationship between two numeric variables is the scatter plot. But there is one alternative that can be useful and is increasingly popular: the slope chart or slope graph.
