2. Opening Assignment  On staff paper, draw the following key signatures  Treble Clef A Major A-flat Major B Major  Bass Clef E-flat Major F Major G-flat Major

3. Today’s Objectives / Agenda  Introduction to Diatonic Harmony  Major Keys  Critical Listening

4. Diatonic Harmony  Diatonic –  Relating only to the notes within the given key signature  Includes 7 distinct tones (in both Major and minor)  2 half-steps  Notes that are not included within the key signature are called chromatic  These diatonic tones are grouped into scales and chords that create melody and harmony

5. What is a key?  A key is the group of 7 notes that diatonically belong to an assigned starting note, called the Tonic  Major Keys  In all major keys, a half-step always occurs between the 3 rd and 4 th scale tones, and the 7 th and 8 th scale tones

6. Key Signatures  Key signatures indicate which pitch-classes need to be raised or lowered in order to create Major or minor diatonic harmony Ex. In the key of D Major, f and c must be raised by a half step in order to maintain the major diatonic pattern

7. Circle of 5ths  The Circle of 5ths is a way to organize key signatures by ordering them according to how many pitch classes must be raised or lowered in order to retain the diatonic pattern

8. Writing Key Signatures  Key signatures must be drawn in a particular way that indicates the order of the sharps/flats (and uses the correct lines on the staff)

9. Goals  Be able to identify all Major Key Signatures  Look at the signature and know what the tonic is  When given a tonic, know how many sharps/flats there are within the key  Know the order of the sharps/flats  Be able to write all Major Key Signatures  Using correct ordering  Using correct lines on the staff
