What we know starting out
- 4-slide PowerPoint is part of presentation, though it is largely pictures of construction. (Benjy Egel)

What we need to learn about:
- Other components in instruments that affect sound (Emma and Camila)

Notes from class/What we have learned so far
Date: Thursday, 4/26/12 Notes: (from Emily Aumann) higher pitch: smaller resonating chamber, shorter wavelengths (shorter pipe, shorter string, tighter string, bottle with more water) lower pitch: larger resonating chamber, longer wavelengths (longer pipe, longer string, looser string, bottle with less water)

Date: Monday, 4/30/12 Notes taken through Scott Gidding: Wider the shake on the slinky, wider the wave (laterally) Wave reflects whether the other end of the slinky is held or not Wave Speed: How quickly it travels down the medium - Making the slinky more tense increased speed - Different materials of medium change speed Same frequency, different wave speed: Slow = shorter wave length Fast = longer wave length

The Deep Blue C's (Emma, Camila, Kathy) 4-27-12 Notes: - Amplitude determines volume - Frequency changes affects wavelength (as frequency goes up, wavelength gets shorter) - Frequency is measured by Hertz (Hz) which is calculated by Waves/Time - Period is the inverse of frequency (Time/Waves)

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

Percussive Instruments
Scott Gidding - Propane tank drum Emma- Bongos (?) Camila- Xylophone (?) Hannah Boney: drum type instrument with a tamberine ring on it.

Stringed Instruments
Kathy- Ukelele Jacob: Harp Connor: Guitar

Hybrids/Other:
Emily: Bicycle wheel harp/percussion
