Introduction
- 注意音乐的走向带来的表达效果
Genres
- A typical symphony is divided into four movements, with respective tempos of fast, slow, moderate, and fast.
- Concertos are generally in three movements.
- theme主旋律，主旋律往往由若干乐句组成，是一种相对完整的音乐结构。motive动机，往往仅由几个音组成，是发展主旋律和整首乐曲所使用的基本素材。比如命运交响曲的开头四个音就是一个动机，整首音乐是对这个动机的发展和演绎得来的。The difference between theme and motive is that theme is the main melody of a piece of music, especially one that is the source of variations while motive is a motif; a theme or subject, especially one that is central to the work or often repeated.
- tone-poem is a one-movement work.
Instruments
- overtone:泛音，不同的乐器有不同的泛音。
- crescendo:(音量)渐强
- disintegration of the sound, low(longer duration)-high-low
- dissonance resolving to consonance. With dissonant intervals they tend to be frequencies that are sounding right next to each other. With space between frequencies it turns into consonance.
铜管乐器
木管乐器
弦乐器
- vibrato:揉弦
- pizzicato:拨奏
