3. Constructing a scale ("just" scale)
freq. ratio of the THE TRIAD:
(major triad) 4 -> 5 -> 6 ( -> 8)
or divide by 4: 1 5/4 3/2 2
C E G C
call first tone of scale C and assign to it a frequency of 1unit
(1 unit can be any number of Hz)
to get Hz, you could multiply by any number you like,
e.g. multiply by 240:
240Hz -> 300Hz -> 360Hz -> 480Hz
why choose these intervals? CONSONANCE!
