Glockenspiel Building - Help me with maths

[marce]

Hi Guys. Im working in build a little glockenspiel with iron bars. They sound very nice. I just can cut them in aproximation and then going slowly tune them.
But i know there are maths that can help make things more quickly.
The problem is that my maths are arechived in my mind from some years ago.

Here is the data i have from four bars i cutted in aleatory way:

Code: Select all

	   hz	    cm 	   gramos
Bar1	832,46	17,8	175
Bar2	1039,5	15,9	157
Bar3	1389,7	13,6	136
Bar4	1885,69	11,7	116

So, i know that with this data im able to predict the hz value to a given weight or size. What i dont remember is "How-to" do that maths.

Any help? Thanks!
