Sposobin and Acoustics Course

Harmony tutorial and key notes are as follows:

Introduction and concepts

Some Principles, Concepts and Bad Phenomena in Harmony Writing of European Tradition and Acoustics.

1. Some undesirable phenomena (1, 2 is vertical, and the rest is horizontal):

1, over-opening arrangement: the interval between 1, 2, 2, 3 in four voices cannot exceed octaves, which will cause the sound to be too open, and beginners should avoid it.

2. Intersection of voices: between adjacent voices of four longitudinal voices, the low voice is higher than the high voice, which is easy to cause voice obstacles and should be avoided by beginners.

3. Sound transcendence

4. Inverse function:

5. Four parts in the same direction

6. Harmony segmentation

7. Parallel five octaves, reverse five octaves, same degree to octave, and octave to same degree.

8, hidden five octaves

9. Tilt

Second, some principles:

1, upper dense and lower sparse principle

2. Internal sound smoothing principle (approach principle)

3. Analyze the music structure and sing more.

4. Complex melody and simple harmony, simple melody and complex harmony

5. Bass melody

6, lateral thinking

Three, some concepts (omitted)

Ps: The above contents should be based on understanding and mastered in the process of practice to avoid rote learning.

Chapter One: major triad, Minor Chord and Quadrant.

One or four harmony writing formats

The text is abbreviated. See handwritten harmony notes for details.

Second, the repetition and omission of the positive triad.

The root sound is only repeated and not omitted (pay attention to the difference between root sound and bass); Three tones are not repeated or omitted; The five tones can be repeated or omitted.

Third, the position of melody sound.

Which note in the triad is called the melody position of this note in the first voice. For example, the root sound in the first part is called the melody position of the root sound.

The chord in the root melody position is the most stable, and the main chord that appears last when doing bass questions should be the root melody position.
