This document provides an overview of music theory concepts related to intervals. It defines major scales as having a consistent pattern of whole steps and half steps. It also lists the order of sharps and flats in a key signature. The document introduces melodic and harmonic intervals and how to count and name intervals based on the number of letter names between the lowest and highest notes. It describes the qualities of intervals within a major scale as either perfect or major and lists which specific intervals have each quality. It also states that if the upper note of an interval is part of the lower note's major scale, the interval will be perfect or major, but may be minor if the upper note is a chromatic semitone lower.

1. Music Theory Unit 3 Intervals

2. Review Major scales always have the same pattern of tones and semitones. It is: The order of Sharps is: The order of Flats is:

3. Review The names of the scale degrees are:

4. Melodic and Harmonic Intervals When the notes of an interval are played one after the other, the interval is called ___________ When the notes of an interval are played at the same time, the interval is called ___________

5. How to count Intervals

6. Naming Intervals All intervals have a specific number, determined by counting the letter names from lowest to highest

7. Interval Quality In a major scale, the intervals are always major or perfect The perfect intervals are: The major intervals are:

8. The really complicated part If the upper note of an interval belongs to the major scale of the lower note, the interval will be either perfect (unison, 4 th , 5 th , octave) or Major (2 nd , 3 rd , 6 th , 7 th ) But what if it’s not? Stay tuned next week

9. Minor Intervals A minor interval is one chromatic semitone smaller than a major interval. If the top note of an interval is one semitone lower than the one that belongs to the scale of the lower note, it is a minor interval Perfect intervals cannot become minor
