Families Theory 7-12
Music theory in interactive widgets
We divided all seven-step interval scales or families into groups. Groups that define the main characteristics of each family. The basis of any family will be one scale or an interval seven-step scheme, that is, a scale of seven notes. Each such scheme will have its own interval structures that are not similar to each other. The scheme of the interval sequence between the steps of the mode and will determine the characteristics of each family. We use the circle to define any such interval pattern. And so, in the evenly tempered system, out of the seven-step scales, only three main architectures can be found. These are two halftones, three halftones and four halftones.
Of all the numerous scales and interval schemes, in a special way it is possible to single out some families that are most used in music. It is worth studying them and determining their proper places both in the field of education and in individual creativity and research.
Two halftone interval architecture
Two-halftone families are interval architectures in which two semitones can be seen in a fret. There are 21 such musical scales, and there are only 3 families. These are the Diatonic family, the Melodic major minor and the Neapolitan family.
Three-halftone architecture
Three-semitone families are interval architectures in which you can see three semitones in a fret. There are many more such scales than two halftone ones, and most of them will be completely unknown. In the example, we will show two well-known ones, such as Harmonic Major and Harmonic Minor. And one family as Untitled-a.
