At the beginning of the class, we continue reading on page 17, Sound Quality. We learned that the sounds made by the human voice and musical instruments are much more complex and sound differently even though some instruments give off the same frequency. In musical terms, the difference between the two waves is called the timbre(TAM-bər), tone colour or tone quality. We also learned that the "Middle-C" on a piano has a frequency of 261.63Hz, but on the Just Scale system, middle C has a frequency of 256, this is what we are going to use.
Diatonic Scale consists of three major triads.
Major Triad is a collection of three notes with frequency in the ration of 4:5:6. If you want to know the frequency of E or G note, you just have to use the ratio between notes (e.i. C note is 256, then the frequency of E note is (5/4)(256) which is 320Hz).
Octave consists of interval between a given musical tone and one with double or half the frequency.We finished reading pages 17-19 and if you want to know some important definitions and summarization of the whole booklet, go to pages 22-23. Finished correcting the homeworks given to use yesterday.
P.S. Anyone wants to scribe for Monday, May 2nd?
