The shorthand formula for intervals is as follows:

1. The pitch distance is called interval, which is divided into melody and harmony.

2. One, four, five, eight, no big or small, two, three, six, seven, no pure.

3. The large pure increase or decrease is the increase or decrease, and the small and large are separated by half a tone.

4. Before adding or subtracting semitones, it was once impossible to subtract.

5. From the second to the octave C root mark, it is very pure and pure.

"One, two, three, four, five, six, seven, eight, ninety": This formula refers to the number of intervals within an octave, that is, the number of intervals from one note to another. For example, the number of intervals from C to G is fifth, and the number of intervals from C to E is third. This formula can be used to quickly memorize the names and numbers of each interval.

"The intervals of major keys: major 2, major 3, 4, 5, 6, major 7, 8; the intervals of minor keys: minor 2, minor 3, 4, 5, minor 6, minor 7, 8 ": This formula refers to the relationship between the sizes of various intervals in a major or minor key.

Techniques

Although intervals are a small knowledge point in music learning, they must be memorized quickly and mastered firmly. You can quickly memorize and master them well through the above formulas. interval.

Ascending melody intervals and harmonic intervals with the same tone are read from low to high and from front to back without any explanation. The direction must be stated when reading the octave of the descending melody interval and the ascending melody interval. If CE is 3 degrees major instead of 6 degrees minor, if the minor 6 degrees should be read as C to E below.
