3. What is the difference between sound and frequency?
 
5. Materials and Aids-
PowerPoint
 
6. Procedures/Methods-

A. Introduction-

1.Overview. A vibrating string can produce a motion that is rich in harmonics (different frequencies of vibration). Bowing the string not only allows a range of expressive techniques, but also supplies energy continuously and so maintains the harmonic richness. However, a string on its own makes little sound when bowing the string not only allows a range of expressive techniques, but also supplies energy continuously and so maintains the harmonic richness. The bridge and body of the violin, and other related instruments, serve to transmit some of the vibrational energy of the string into the air as sound. The way in which they do so is important to the sound of the violin family of instruments.

Definition of sound vs frequency

Example of loudspeakers
 

B. Development-

1. Strings: 4 different string, all same length. Different gauge/width allows to produce difference frequencies in correlation to position on the instrument.
2. The Bridge: Acts as an amplified, it catches the vibrations of the strings and transfer them "inside" the violin.
3. The soundpost and bass bar: The post and bar act as the bridges translator, lower frequencies will be transferred through the bass bar and thus become resonate as do the higher frequencies transfer to the sound post to produce higher pitch.
4.) The body: When we yell into a cavern, what do we hear? An echo! This is similar to a violin acoustics the vibrations of air movement are being moved rigorously and thus escape through the F-holes to produce sound and pitch!
 

C. Practice-

1. Point to specific anatomic regions of the violin and ask class to identify: Bridge, neck, etc.
2. Pass Violin around the room, so that students are engaged with the subject at hand.
3. Empty water bottle, blowing over the top to produce sound through the disturbance of air.
 

D. Checking for understanding-

E. Closure-

Questions and Answers, after presentation!
 
7. Evaluation-
1. Students are able to differentiate sound and frequency
2. Students are able to explain in their own words how a violin a capable of producing sounds with various frequencies.
