The correct term for fourths, fifths, and octaves in a major scale is "perfect interval."
In a major scale, the fourth, fifth, and octave intervals are defined by the term "perfect interval." To understand this, let's break it down:
1. Start with a major scale: A major scale consists of seven notes, with the eight note being the octave of the first note.
2. The fourth interval: Counting from the first note of the major scale, the fourth note is called the "subdominant." It forms a specific relationship with the tonic (first note) and is called a perfect fourth.
3. The fifth interval: Counting from the first note of the major scale, the fifth note is called the "dominant." It forms a specific relationship with the tonic and is called a perfect fifth.
4. The octave interval: Counting from the first note of the major scale, the eighth note is called the "octave" and is exactly double the frequency of the first note. It forms a specific relationship with the tonic and is called a perfect octave.
So, in summary, in a major scale, the fourth, fifth, and octave intervals are defined as perfect intervals.
