The air you breathe is made up mainly of nitrogen and oxygen. Helium is much less dense than regular air. That's why helium is used in baloons to make them float.
Due to its lower density, sound travels over twice as fast through helium than it does regular air. When you breathe in helium, your voice travels much more quickly across your vocal cords. This results in the funny sounds you make when you talk after breathing helium.
Some people think that the helium changes the pitch of your voice. In reality, however, your vocal cords vibrate at the same frequency. The helium actually affects the sound quality of your voice (its tone or timbre) by allowing sound to travel faster and thus change the resonances of your vocal tract by making it more responsive to high-frequency sounds

Indicate two things you can do to increase the intensity (sound pressure level) of your voice and two things you can do to increase the fundamental frequency of your voice. Why would you do each action? Be sure to distinguish which two you would do for raising intensity (perceived as loudness). and which two you would do for raising fundamental frequency (perceived as pitch).

Questions: 1. Explain how you can raise the pitch of a note on a guitar by altering the string’s (a) length, (b) tension, or (c) thickness or mass. Be very specific about what you would do to raise the pitch. 2. If the fundamental frequency of a guitar string is 250 Hz, what is the frequency of the second harmonic? Of the third harmonic? Explain. 3. Consider a vibrating guitar string. The loudest harmonic is the fundamental, but many higher...

You will complete this project by implementing one class.
Afterwards, your program will play music from a text file.
Objectives
Working with lists
Background
This project addresses playing music. A song consists of notes,
each of which has a length (duration) and pitch. The pitch of a
note is described with a letter ranging from A to G. 7
notes is not enough to play very interesting music, so there are
multiple octaves; after we reach...
