What we know starting out

 * 1) Instrument must be able to produce eight different notes, creating a scale. CP
 * 2) Different instruments will be able to make different notes and chords, and eventually they should come together to make a song. CP
 * 3) We have to preform a song with our team and each of us has to have different instrument. S Perry
 * 4) Were making bands JS
 * 5) All instruments must be playable by everyone and easily transportable. SE period 2
 * 6) Different instruments may be more suitable to certain songs -E Conant p.2
 * 7) That there are many different interpretations as to what music exactly is, and this is partially up to our personal interpretation. S. Panek, 2

What we need to learn about:

 * 1) What a scale is, CP
 * 2) how to make different notes, CP
 * 3) how to build different types of instruments with different sounds. CP
 * 4) How different instruments make music and
 * 5) how to change the pitch on the instruments to make different noises. S Perry
 * 6) How to play our instrument. JS
 * 7) The physics behind sound vibrations and how that relates to music. Scott Panek, 2
 * 8) What types of wood (other materials) make good acoustics, and what size the instrument must be in order to be loud enough. Scott Panek, 2

Notes from class/What we have learned so far
Date: Notes: Vibration is the source of all sound CP Vibrations in time and space are waves CP Soundwaves are longitudinal rather than transversal CP Sound is transmitted through air (at 343m/s 20 degrees celcius) slower than it is through water or metals (and other solids) CP The speed of sound through a certain medium depends on the medium's elasticity CP Period = # of seconds/wave CP Frequency = # of waves/second CP Frequency = velocity/wavelength CP Volume is directly proportional to amplitude CP The human ear can detect sound between the frequencies of 20 and 20,000 hz CP Length (physical) = Length (acoustical) -- r*(.61)*(# open ends) CP Mr. Ronneberg is really cool. CP What a node is- MB What an antinode is- MB The effect of changing a node on a xylophone-MB How to calculate the frequency of any object- MB How to determine the calculations of the specific instrument using the new found frequency- MB

[|This website can paly the differnet notes for you and has more information if you search though the website.] S Perry

[|http://www.home.earthlink.net/~graypoodles/kkboxguit.html] This site goes into a detailed description of the building process of many different kinds of instruments, ranging from the simple (rubber band guitar box) to the complex (hand piano). You will find visual images, material lists, and step-by step guides for building. S. Panek, 2

[] This link takes you to a site that goes into the science of music. It talks about the different things that factor into sound, such as pitch and timing. It also goes into musicality, which is a factor that defines how "good" music is. S. Panek, 2

http://www.oddmusic.com/gallery/index.html For anyone who wants to build a more abstract instrument, this website has a several unique instruments to build or get ideas from. ADW

[|Wikipedia article on Sound. Very helpful for sound basics and an overview of sound concepts.] CP

Initial building Ideas:
-EC
 * 1) percussion resonance instrument
 * 2) pan pipes
 * 3) guitar/ other string instrument

Final list of Who is building what
This is a list of who is building what, add yourself to the list. If you are building something similar to someone else in the class (or any class for that matter), you can discuss ideas or problems with them
