Read Chapter 20 in your book on musical sounds. do you have any questions?
Why does the pitch of a guitar string change when you use your finger to press the string to the neck of the guitar?
The wavelength of a sound wave is the
the frequency of a sound wave is
The amplitude of the sound wave is (check all that apply)
A flute, a violin and a trombone all play the note "A". The conductor plays a tone generator that produces a perfect 440 HZ pitch. All the three instruments correctly match the pitch, but it is very very easy to tell which sound is the flute, which one is the violin, which one is the trombone, and which one is the tone generator. If they are all producing a 440 hz tone, how can you tell them apart?
A violin string vibrates a 440 hz. what is the period of the string's ocsillations?
If the fundamental frequency is 440 hz, what is the frequency of the first harmonic?
explain the difference between analog and digital.
Go to https://phet.colorado.edu/sims/html/fourier-making-waves/latest/fourier-making-waves_all.html and spend some time on the wave game - your goal here is to see how different harmonics add together to make specific get at least one star for 1 wave, 2 wave and 3 waves. one extra credit point on a test for someone who can get a star on 4 wave, 2 more points for a 5 wave. upload the picture of your stars in the background below.
