Perfect Fourths
Perfect fourths play a vital role in scale and chord construction. In this lesson we explore the concept of the Perfect fourth, one of the most common and stable intervals in Western music. Spanning four letter names and measuring five half steps, the perfect fourth is easy to recognize both visually on the staff and aurally. The video explains how to identify a perfect fourth, both by counting steps and by observing the distance between notes.
Examples of perfect fourths include C to F and A to D—intervals that span from a line to a space or vice versa. The lesson also highlights the use of perfect fourths in familiar melodies and their foundational role in harmony. Understanding perfect fourths strengthens a musician’s interval recognition skills and deepens their comprehension of scales and chord structures.
