1. Introduction to Music Theory Intervals

2. The Keyboard Half StepsWhole Steps

3. Musical Alphabet in relation the keyboard  ABCDEFGA (Repeats after G)  These notes can be modified by using ACCIDENTALS # means to raise the note a half step b means to lower the note a half step C D E F G A B C#/ D#/ F#/ G#/ A#/ Db Eb Gb Ab Bb

4. Musical Alphabet in relation to the keyboard  Enharmonic- Two notes that look different but sound the same. Ex.

5. Intervals  Interval- The relationship between two notes  Types of intervals  Harmonic- Two Notes played at the same time.  Melodic Interval- Two notes played separately, one after the other.  Melodic  Harmonic

6. Properties of Intervals  Quantity- The distance between two notes Unison, Second, Third, Fourth, Fifth, Sixth, Seventh, Octave

7. Properties of Intervals  Quality- Gives us a more specific description of the interval. Determined by the number of ½ steps between the notes.

8. Qualities of Intervals  Major (M)- used only with seconds, thirds, sixths, and sevenths. ½ step more than a minor interval.  Minor (m)- Used only with seconds, thirds, sixths, and sevenths. ½ step less than a major interval.  Perfect (P)- Used only with unisons, fourths, fifths, and ovtaves  Diminished (d)- Can be used with any interval quantity except unison. ½ step less than a minor or perfect interval.  Augmented (A)- Can be used with any interval quantity. Half step more than a major or perfect interval.

9. How to identify Intervals  Identify your two notes and write their names.  Count the number of notes between the two(including both notes).  Find the notes on your keyboard.  Then count the number of half steps (on the keyboard) between the two(don’t include the 1 st note).  Use your chart and find the number of half steps(semitones) to identify the interval.
