2. 2-4 Quality and Sound Sound quality is also called timbre Every sound produced has a fundamental tone which is the overall pitch or frequency of a tone. Also along that fundamental tone there can be higher frequencies called overtones. Overtones give a sound its identifiable characteristics. Flute compared to an oboe. The overtones create a sound’s timbre.

3. Music vs. Noise Music has an identifiable pitch (fundamental tone) Music has rhythm – a repeating pattern Music has a pleasing quality (relationship between the overtones and fundamental tones) Noise does not have any of the above. Are there sounds that are neither music nor noise?

4. 4 Groups of Instruments Brass – Columns of air are vibrated by lips buzzing. The longer the column of air the lower the pitch. Example: Trombone Woodwinds – Columns of air are vibrated by a reed or air being blown over an opening. The longer the column of air the lower the pitch. Example: Flute

5. Percussion – a vibration is created by an object being struck Pitch can be changed by tightening the membrane that is being struck. Example: Snare drum Stringed instruments – Strings are either rubbed, or plucked to create a vibration A higher pitch is produced when the string is thinner, tightened, or shortened. Example violin What group does a piano fit into?
