Intervals

Intervals

            Name of the intervals between two notes are to determine as how many note names are between this two notes. Name of the intervals between C and  E is a third interval. Because its about three note names called C, D and E. However, there are nine types of intervals that are named major, minor, perfect, dimnished, augmented, doubly dimnished, doubly augmented, unison and octave. In harmony, this adjectives is important for describing name of chords. Ex.9 is show that what kind of intervals have and how many steps and symbols have.

Intervallic Inversions

           

            Intervals can be named upwards to downwards. In this case, names of intervals can be changed. In that point, number of "nine" helps to check the names. If an interval is a second, inversion of second is the seventh. Seven plus two is nine so calculation is okay. If an interval is major, inversion must be minor. The chart in ex.10 shows all the changes.
