This mean duration is relative to the opposite of the solid theme of the frequence .
step 3
produce either a major or a nonaged pentatonic plate .
you might equate the two graduated table by play only dark cay on the pianissimo .
For the venial pentatonic graduated table , set out with D precipitous , then toy the next four eminence .
For the major pentatonic scale of measurement , pop out with F precipitous .
footfall 4
habituate the next frequency ratio .
On the major pentatonic shell , the 2nd eminence has a 9/8 frequency proportion ( 1.125 ) , the third bank bill has a 5/4 absolute frequency proportion ( 1.25 ) , the 4th bank note has a 3/2 absolute frequency proportion ( 1.5 ) , and the 5th short letter has a 5/3 frequence proportion ( 1.6667 ) .

The frequency ratio of the underage pentatonic plate are 6/5 ( 1.2 ) , 4/3 ( 1.333 ) , 3/2 ( 1.5 ) and 9/5 ( 1.8 ) .
footprint 5
Plug in your original tube distance and the major or underage frequency ratio into the rule in Step 2 .
This will give you the length of your remain pipe .
If your first pipework is 30 curium , for lesson , the third greenback on your major pentatonic weighing machine would match 30/(1.25)1/2 or 26.8 centimetre .
