**The Fender Rhodes Electric Piano / Rhodes Tine Length Curve**

« **on:**February 10, 2019, 03:43:51 PM »

Hi all, i've been searching and searching for this topic and couldn't find anything. If you can link me to a previous topic that would be much appreciated. I apologize if it's been discussed before.

My question is in regards to the tine length charts that i've seen. Is there any reason why they are not nice smooth curves? Instead they look like someone traced them after the fact. Was it so that someone could use a ruler and the lengths were rounded to nearest fractions?

The nerd in me wanted to find a formula for the curve, so I threw all the tine lengths I found in a previous post in excel to see which tines had the most "error" in lengths.

The formula I found to fit the best was an exponential formula, and it came out to

y=7.573e^-.027x

where "x" is the key number and "y" comes out to the length. In this formula "e" is Eulers number (2.71828), not "times ten to a power"

What I found is that the tine lengths are on average .027" off. The one I found to be the farthest off is key 19. It is .081" off of the curve. The closest one was within .001", key 42. I can't upload my spreadsheet but i'll post a picture later.
