types of intervals music
Intervals are one of the essential elements of music, the building-blocks that make up its structures. Melodies, scales, and chords are all patterns of melodic or harmonic intervals, and the notes in any given key belong to that key because of their interval relationships.
Remember, perfect intervals have only one basic form. The first (also called prime or unison), fourth, fifth and eighth (or octave) are all perfect intervals. On the other hand, non-perfect intervals have two basic forms.
Major intervals comes from the major scale. Minor intervals are exactly a half-step lower than major intervals. Here's a handy table that will make it easier for you to determine intervals by counting the distance of one note to another note in half steps. Table of Intervals.
