2. TODAY:  Music Sharing: Justin (CHS)  Review:  Rhythm Hierarchy, note values, & rest values  How Music is Organized:  Measures, Bar lines, & Double Bar Lines  Time Signatures:  4/4 Time, 2/4 Time, & 3/4 Time  ET2

3. TO REVIEW…

5. HOW MUSIC IS ORGANIZED…  Music is divided into equal parts by BAR LINES.  The area between two bar lines is called a MEASURE or a BAR.  A DOUBLE BAR is written at the end of a piece of music. It is made up of one thin and one thick line, with the thick line always on the outside.  On a GRAND STAFF, the bar lines and the double bar pass through the entire staff.

6. SOME EXAMPLES:

7. TIME SIGNATURES  The TIME SIGNATURE appears at the beginning of a piece of music immediately after the clef sign.  A TIME SIGNATURE contains two numbers, one above the other.  The upper number tells how many beats (or counts) are in each measure.  The lower numbers tells what type of notes receives one beat.

8. 4/4 TIME:  In 4/4 time, the top number means there are 4 beats in each measure.  In 4/4 time, the bottom number means that the quarter is receiving one beat.  4/4 time is also called “common time.”  In 4/4 time, a QUARTER NOTE is equal to one beat.  In 4/4 time, a HALF NOTE is equal to two beats.  In 4/4 time, a WHOLE NOTE is equal to four beats.

9. 2/4 TIME:  In 2/4 time, the top number means there are 2 beats in each measure.  In 2/4 time, the bottom number means that the quarter is receiving one beat.  In 2/4 time, a QUARTER NOTE is equal to one beat.  In 2/4 time, a HALF NOTE is equal to two beats.  In 2/4 time, a WHOLE REST is used for a full measure of rest, even if there are only 2 beats in each measure.  A HALF REST and a WHOLE NOTE are never used in 2/4 time.

10. 3/4 TIME:  In 3/4 time, the top number means there are 3 beats in each measure.  In 3/4 time, the bottom number means that the quarter is receiving one beat.  In 3/4 time, a QUARTER NOTE is equal to one beat.  In 3/4 time, a HALF NOTE is equal to two beats.  In 3/4 time, a WHOLE REST is used for a full measure of rest, even if there are only 3 beats in each measure.  A HALF REST and a WHOLE NOTE are never used in 3/4 time.
