Whats the difference between perfect and major?
The only significant difference between major and perfect labels for intervals is the consonance or harmonic sound quality of the perfect intervals. For practical application the perfect 4th and 5th are major intervals.
How do you know if its a perfect interval?
Perfect intervals have only one basic form. The first (also called prime or unison), fourth, fifth and eighth (or octave) are all perfect intervals. These intervals are called "perfect" most likely due to the way that these types of intervals sound and that their frequency ratios are simple whole numbers.
Why is it called a perfect interval?
The label of “perfect” in addition to a number describes the interval's quality. These intervals are called perfect because the ratios of their frequencies are simple whole numbers.
