what are the different musical forms?differntiate one from the others.

Strophic form is most commonly seen in popular music, folk music, or music that is verse based. This is because the material is repeated so much. Each of those A’s represents a short verse, normally 8 to 16 measures long.

Through-composed form is a composition that is entirely continuous. Any large scale thematic material is not repeated, and each section sounds like something completely different. An example of this would be ABCDE.

Binary form is music with an A and B section. While the material is different in each section, it’s closely related.

Ternary form is defined as ABA structure. This means the piece starts with the main theme, goes to contrasting material, and then returns with that exact main theme material to end it.

Rondo form is ABACA or ABACABA. The most common forms are the 5-part and 7-part Rondo. What you’ll notice about rondo form is that each section returns to the A section. However, as the sections progress, new material is added in between each A section.

Arch form is ABCBA. It carries this name because the structure of the music moves in the form of an arch. There is new material in each of the first three sections. Once it reaches the C section, the music simply moves in reverse order. It goes back through the B material and concluding with the main A theme

Sonata form is a musical structure consisting of three main sections: an exposition, a development, and a recapitulation. It has been used widely since the middle of the 18th century.
