First Form Week 11 Music November 15 – 19, 2021 Topic: Bars (measure), bar lines, double bar lines, final double bar line Subtopic: Stem directions

1 At the end of the lesson you should be able to: 1. Give a reasonable definition for bars, bar lines, double bar lines and final double bar lines 2. Identify these in musical score you see. 3. Identify the repeat sign and show how it is used in music. 4. Write time values on the musical staff making sure to follow the stem direction rule. 5. Use your knowledge gain from lesson to create a two bar rhythm.

2 Important keywords, symbols and definitions for you to know: Bar (also called measure) - in music, a bar is the spaces and lines where the notes are written Figure 1 Remember that the time signature below is also called common time. We can write the time values onthe lines and in the spaces. in the spaces

3 Bar line: The bar line divides each bar or measure into equal units. Figure 2 In figure 2 notice how the Bar lines are not doubled. (They are instead single and run vertical through the staff. Try not to mix them up with the double bar lines. Double bar lines: Two lines (A symbol in musical notation used to separate two sections or phrasesof music, and to start and end a musical piece). We will explore more on double bar lines in term two. Figure 3 The double bar line can be used in apiece of music to separate two sections or phrases. Try not to mix itup with the final double bar line, as shown in figure 4.

Figure 4 4 The final Double bar line should be place at the end of the music to state that the music has come to an end. Notice how it has a thin line at the front and thicker one at the back The Repeat sign – The repeat sign is used to tell the player or singer to repeat a section of the piece. If the piece has only one repeat sign, then that means to repeat from the beginning,and then continue on (or stop, if the sign appears at the end of the piece). The repeat sign can also be placed in the middle or end ofthe music.

5 Stem direction of notations Rule # 1: if a note is on the middle line of the staff, the stem can either go up ordown Rules # 2: if a note is below the middle line of the staff, the stem should go up Rule # 3: if a note is above the middle line of the staff, the stem should godown. Let’s look at these examples

Half note with stem up and down 6 Quarter note with stem up and down Eighth note with stem up and down sixteenth note with stem up and down Important to note students: When drawing stems upwards, they should be placed on the right side and on the left side when you are drawing them downwards, as shown inthe time values above.
