MUS 101 Lecture Notes - Lecture 4: Tritone, Major Scale
Document Summary
Melodic interval: the distance between two notes played one after another. Harmonic interval: the distance between two notes played at the same time. Perfect interval: the intervals of a fourth, fifth and octave are perfect, and are present in both major and minor keys. Perfect intervals cannot be major or minor in quality; they can only be altered through diminuition or augmentation. Major: the interval of a second, third, sixth, or seventh that is formed above the tonic note of a major scale. Major intervals have a happy sound, just like the major scale. Minor interval: the interval of a second, third, sixth, or seventh that is one half step smaller than its equivalent major interval. Augmented: an interval that is one half step larger than a major or perfect interval. Diminished: an interval that is one half step smaller than a minor or perfect interval. Tritone: an augmented fourth or a diminished fifth.
