Are you familiar with the term “diminution” in music theory? If you’re not, don’t worry! In this article, we’ll dive into what it means and how it’s used in music.

What is Diminution?

In music theory, diminution is a technique that involves dividing a long note or a series of long notes into shorter, faster-moving notes. This can be done by using various rhythmic subdivisions such as triplets or sixteenth notes. Diminution is often used to add ornamentation and interest to a melody or to create intricate, virtuosic passages.

The History of Diminution

Diminution has been used since the Renaissance era and was particularly popular in Baroque music. Composers such as Johann Sebastian Bach and George Frideric Handel were known for their use of diminution in their compositions.

During the Baroque era, performers were often expected to improvise their own embellishments and diminutions on written melodies. This practice was known as “divisions” and was seen as an important skill for musicians of the time.

Types of Diminution

There are several types of diminution techniques that can be used in music. Some common examples include:

The Purpose of Diminution

Diminution serves several purposes in music. It can add interest and ornamentation to a melody, create virtuosic passages for performers, and showcase the skill of the performer. Diminution can also be used to highlight important harmonic progressions or to create tension and release within a piece of music.

Examples of Diminution

One famous example of diminution can be found in Johann Sebastian Bach’s “Goldberg Variations.” The aria that begins the piece is later repeated with intricate, virtuosic variations that use diminution techniques.

Another example can be found in George Frideric Handel’s “Messiah.” In the aria “Rejoice greatly,” the singer performs elaborate runs and trills using diminution techniques.


Diminution is a technique that has been used in music for centuries. It involves dividing long notes into shorter, faster-moving notes to add ornamentation and interest to a melody. Whether you’re a performer or a listener, understanding diminution can help you appreciate the intricacies and beauty of Baroque music.
