B to Bb Change-Tempered Tuning?

Michael Frede · Post by **Michael Frede** » 11 Sep 2003 8:09 am

Is there an established tempered tuning for 5th & 10th when lowered to Bb?If so,what is it?THANX.

For just intonation, it should be a major third above the 7th string F# (it's actually an A# note, not a Bb). So, take the A-440 offset of your F# and subtract 15 cents.

In other words, if your F# is tuned to -5 cents, the A# should be tuned to -20 cents.

Here's a tougher question for those who tune the split: what is the tuning of the C note that you get from A+X?

I cannot use the split using the B to Bb lever and the A pedal. Here is why. The split comes out toooo flat on my guitar. This means when I sharpen the split to bring the C into tune, my Bb note is too sharp, and NO way to correct it; since all splits work on the premise that the full lowered note comes out too flat..

If it would work, I would tune the C "split" to be JI with the E and/or the A notes (B pedal down).

Some guitars can do the split - some can't but it's always gonna be easier and faster to get that C with a half pedal.Plus that way,you can temper it perfectly into tune with whatever other notes are being used.It's just like bending a string into tune on a standard guitar - a skill easily mastered by teenagers with nose rings.

I can't half pedal nearly close enough.

Nor can I Ernest. Never have been able to. I admire those that can.

I used to use that half pedal a lot.
True, it works good on some guitars but not all.

I remember in the 70's my A pedal worked real good on the half tone (C)on my PP Emmons.

I am getting a good half tone (C)on my MSA S12 "Universal" Lacquer wood guitar right now. I like it.....al

Topic drift. I suppose it's my fault for asking about the split.

I'm surprised to see LeRoy tuning the change so sharp. Wouldn't it be out of tune with the F# string at that setting?

Carl, you can still do your splits by adding extra lowering rods to your A pedal.

Tune the A#'s as usual. However with this method you tune the C split with the raise rod, which in your case will make your C#'s sharp when you let off the lowering lever. With the A pedal activated, lower the C#'s back to pitch with the extra lower rods.

The extra lowers will only move a little, and if you put the pulls as low on the shaft as possible, you probably won't even feel it.

Hi Jim,

hmmmmmmm

I am going to have to think and study about this. It sounds very interesting. Never thought about that or heard about it before.

Thanks soo much for telling me about it.

May Jesus richly bless you my friend,

As usual,you are correct b0b.I use Jeff Newman's tempered tuning for E9 which has the F#'s at +6.By tuning the Bb's(or A#'s if you prefer)to -10(or -16 in relation to the F#'s),sounds perfect.Thank you.
