The Pipe-a-Phone Project Blog : Victor N. 8B Summary Frequency is the rate at which waves pass in a given time. Pitch, however, is the highness or lowness of a note. The relationship between the two is that frequency influences pitch. If there is a low frequency, there will be a low pitch. The appearance of the wave changes with a change in the pitch because of the higher the pitch the shorter the wavelength. The appearance of the wave changes with a change in the volume because the louder the sound, the larger the amplitude. When you play higher notes, the waves are closer together. Yet, when you play louder, the waves are taller. 'Musical instruments create sounds that can be varied in pitch and volume.' Some instruments give pure tones while some produce a mix of frequencies. Musical sounds are created from vibrations from the device in the instruments. Our task is to use what we know about musical waves and sound and to create an instrument that could play 8 tuned ...

Weekly Blog : Victor N 8B Image Location Summary 'Musical instruments create sounds that can be varied in pitch and volume.' Some instruments give pure tones while some produce a mix of frequencies. Musical sounds are created from vibrations from the device in the instruments. Those devices are wires in string instruments like guitars, drums, and/or reeds in woodwind instruments such as clarinets, oboes, and saxophones. Wires in instruments can affect the tune and frequency of the sounds. They create music when you tap or pluck the string, which vibrates and create compression waves in the air. The sounds of drums are created when striking the head, which vibrates and create sounds. Finally, reeds create sounds when you use your tongue and blow on it, which vibrates and create music. In conclusion, musical instruments create sounds from vibrations and can have different pitches and volume. SP2 - Using Models This week, I used models to demonstrate my understandin...
