The arrangement of left-hand chords is a very important part of the composition and performance, which directly affects the color, style and emotional expression. Here are some basic principles and methods of left-handed chord arrangement to help you better understand and use chords.
1. Understand the style and emotion.
Before arranging chords, it is important to understand the style and emotion of **. Different styles and emotions require different chords to be arranged. For example, Romanticism typically uses more complex chords and melodies, while Classicism focuses more on harmonic stability and structural rigor. When arranging chords, it is necessary to take into account the emotional expression of **, and choose the harmonious and discordant intervals that can express the corresponding emotions for combination.
2. Determine the basic framework.
When arranging chords, the first step is to determine the basic framework. This framework is usually made up of major, genitive, and subordinate chords. The main chord is the center of a tonality, with the genus chord leaning towards the main chord and the subordinate chord leaning towards the genital chord. This framework can be modified and extended on a case-by-case basis, but in general, it is a stable foundation that can be used as a reference for other chord arrangements.
3. Use alternative chords.
When arranging chords, you can use alternate chords to enrich the color. Substitution chord refers to replacing the original basic chord with other chords to achieve a different ** effect. For example, in C major, an em chord can be used instead of an am chord for a warmer, softer sound. When using alternative chords, be careful not to disrupt the original harmony, but also consider the adaptability of the style and the expression of emotions.
Fourth, use extended chords.
Extended chords refer to adding extra notes to a basic chord to add momentum and tension. For example, in C major, a ninth can be added to a genitive chord for a more intense instabilities. The use of extended chords can break the original sense of harmony and increase the tension and tension of **. When using extended chords, care should be taken to control the frequency of their use, so as not to upset the balance of the entire structure.
5. Consider bass coherence.
Bass coherence means that the connection between the bass parts should be smooth and natural. When arranging chords, pay attention to whether the connection between the bass parts is smooth. For example, in C major, a progression of C-F-G-C can be used to guarantee bass coherence. Bass coherence can make the whole **sound more smooth and natural, and enhance the appeal**.
6. Use parallel chords.
A parallel chord is a chord that has a common tone within an octave. The use of parallel chords can increase the sense of hierarchy and three-dimensionality. For example, in C major, a progression of C-DM-EM-F can be used to add layering to the **. Be careful not to use parallel chords too often to avoid confusion. At the same time, it is necessary to pay attention to the harmony between the parallel chords, so as not to upset the balance of the whole **.
To sum up, left-hand chord arrangement needs to take into account factors such as style, emotion, frame, alternate chords, extended chords, and parallel chords. In the actual allocation process, these principles and methods should be flexibly used according to the specific situation to achieve the best results.
