Theme & Variation in Music: Definition, Form & Examples

Lesson Transcript
Instructor: Erika Svanoe

Erika has taught several college music courses and has a doctorate of musical arts in conducting.

In this lesson, you will learn about theme and variation in music. You will also learn about its form, as well as what differentiates a theme from a variation.

What is Theme & Variation?

Theme and variation is a specific kind of form in music. The form of a piece of music tells you how the music is organized. With a theme and variation, the piece begins with a theme that is the main melody. That is followed by one or more variations of that melody. A variation is music that is similar to the theme but is also different enough that it does not repeat the melody exactly.

The form of a theme and variations consists of a melody, or theme, followed by variations of that melody. Composers often use theme and variation to write an entire piece or to write one movement of a larger piece. It is most often used in instrumental music.

You can think of a theme and variations in a musical piece like cupcakes and the additional ingredients used to decorate them. You start with a basic cupcake (the theme) and then add some type of decorations on top (the variations). Some cupcakes might have frosting, some might have sprinkles, and some might have a creamy filling, but they are all still basically cupcakes.

There are two ways that the sections of a theme and variation are labeled. Sometimes the composer will simply label the sections in the music 'Theme,' 'Variation 1,' 'Variation 2,' and so on. You can also label the sections of the form by calling the theme the A-section, and then labeling each variation as 'A1,' 'A2,' 'A3,' and so on. Each 'A' indicates the same musical material is being used, while each number after an 'A' indicates that the section is a variation of 'A.' Let's take a closer look at each section of theme and variation.

The Theme

The theme is the first main melody that you hear. It is the melody that the rest of the music will be based on. Sometimes the theme does not start immediately at the beginning of the piece but is preceded by an introduction. An introduction is a short statement of music that comes before the actual form of music begins.

The theme is usually the simplest sounding melody of the piece. If we think back to our cupcakes, a cupcake that represents the theme would have no decoration, frosting, or filling. It would be the simplest version of the theme.

The Variations

A variation is music that is based on the original theme but is somehow different. A composer can vary the theme by changing the rhythm, changing the harmony, or by decorating the melody by adding additional notes. As long as the music is similar to the theme but not the same, it would be considered a variation. So, if the baker takes a plain cupcake and puts chocolate frosting on it, this would be a variation. If they put powdered sugar and sprinkles on it, this would be another variation.
