Diddley Blog
In our STEAM class, LST, we have covered the L (Light) and moved onto the S, Sound. Like light, we have learned about waves in this unit, given the fact that waves are what make each sound unique. We went over sine and cosine waves, wavelength and frequency, and other things that are more exclusive to sound, like asin (bx + c) + d and the anatomy of the ear. For this action project, we were assigned to make a diddley bow. A diddley bow is a one stringed acoustic guitar built upon a plank with an open tin can as a resonator on the opposite side. The sound hole (open side of the tin can) amplifies the vibrations from the string as it is plucked. The images below will give you a better grasp of how the bow is assembled. Diddley bows originated in the South and became a big influence on the blues. Why were we assigned to make an instrument for the AP of our sound unit in LST? Instruments are great demonstrators of producing varying sounds, with some of them being quite harmonic...
