Preparing for Success in Music Theory

Welcome to the music theory website at Iowa State University. The music theory courses at ISU provide an excellent foundation for you to become a better musician through becoming skilled at interpreting and understanding music as well as writing and arranging music. 

We want you to thrive in music at ISU in all aspects—performance, academics and service. To succeed performance and academics, it is essential to be fluent in the fundamentals of music prior to entering the degree program. Several resources that can help you with this are listed below. To make sure you are ready to begin taking the required music theory classes for your music major, you will take a diagnostic theory exam the first day of class to determine if you have any knowledge gaps that need to be addressed. If you do have any gaps, you will be advised to take a short Theory Preparation course at the beginning of the semester alongside the regular theory course for majors. This course will help ensure that you have a successful start in music theory. 

The following are fundamental skills needed for beginning the core theory classes for music majors. These include links to tutorials to learn about these skills and to practice building these skills.
