To be classified, examples are as follows:

1. Rhapsodies

mostly have distinctive national colors and narrative paragraphs, such as Liszt's hungarian rhapsody No.2, Enescu's Romanian Rhapsodies No.1 and Ravel's orchestral Rhapsodies.

2. Narrative songs

generally refer to narrative and dramatic solos or solos. The word ballad comes from Latin ballade, which means dancing. It was originally a dance song. After the 14th century, singing without dancing became a general term for solo or polyphonic narrative songs in France, Italy, Britain and Germany.

3. Sonata

The first movement: Allegro movement, sonata form.

the second movement: adagio, variation, polyphony or free sonata.

the third movement: minuet or scherzo, with three complex forms.

The fourth movement: Allegro or Allegro, sonata or Rondo.

4. Concerto

The two factors are both competitive and cooperative. Concerto first appeared as a vocal genre. In the 16th century, it referred to an Italian acoustic music accompanied by musical instruments.

5. Capriccio

Its musical structure is free, random and full of vitality. In the 16th century, it refers to the multi-voice music in pastoral style and instrumental music using polyphonic music expressions such as imitation counterpoint, which often has the nature of title music.

6. Prelude

Before the suite, the general performer has to improvise for a short time before playing, which gradually evolves into an art form. Prelude is also used in opera to replace overture, which is free in form, generally based on the music in the play and used before the center.
