The two threads on anatomy of a slant and the baritone Weissenborn got me thinking.

I have been doing a lot of reading and study on how to get started. I have some material by Jerry Byrd, where he strongly recommends a short scale instrument. He says this is necessary to make all of the slants he uses possible. From geometry class they say that any two points determine a straight line. It would seem that two note slants could be made on any scale length, as long as the notes were within the length of the bar. Am I correct in assuming that he is actually talking about 3 note slants, when he says you need a short scale instrument to accomplish them?

I know that as a beginner I won't be worried about 3 note slants for quite a while, I was just currious. Thanks -- Jim

The difference between a long scale and a short scale is only about one fret. How much harder is it to do a slant at the first fret, compared to the second fret? Not much I would guess.

The ratio of string spacing to fret width is more accurate for 3 note slants on a 22 1/2" scale than it is on longer scales.

There are other variables - such as accuracy of bar placement, smoothness of vibrato and condition of strings . .

Oakley Hicks did an analysis between these three steels a few years back:

JB Frypan ... 22" scale
Ricky B6 .... 22.5" Scale
Sierra Laptop ... 24.25" scale

http://steelguitarforum.com/Forum2/HTML/002364.html

Its all about the ratio of scale length to string spacing ...

How does the width between the strings factor into the equation? Is it better to have the spacing at the bridge and nut equal? Thanks in advance.

The distance between the strings is just as important as the distance between the frets.

Think of it as a triangle ... where the distance between 2 frets is "a" and the distance between the 2 strings is "b". Your bar is the hypotenuse.

The angles are associated with the lengths of "a" and "b".

"Split slanting" ... is where the short scale and string spacing determine what is actually possible to do with the tip of a bar.

This is why JB used the short scale.

I also believe he designed the JB frypan to be a 22" scale ... so he could get 8 strings on it ... and still have the same geometry of his B7.

Andy ... heres a nice discussion on Equal spacing at the Nut and Bridge ...

So i.e., to do JB stuff on a 26" scale, we need both proportionately wider string spacing and a proportionately bigger bar. I guess bigger hands wouldn't hurt either.

The amp can probably stay the same size, though.

Seriously ...

Split slanting" is at the heart of this "issue" ... as far as JB's recommendations on scale length, string spacing and bar size.

Also, those chords he sometimes fudges in C6... like the reverse slant dom7th chord (3rd, root, and flat 7th on strings 2, 4, and 5 respectively) that conveniently resolves by straightening the bar.

Yeah ... ain't just that one either ...

Slants may "line up" correctly using a straight edge ... but once you factor in the "Just Intonation" deviations ....

Well, lets just call alot of "3 note slants" ... Studies in Approximation ...

From Slantin' in C6/A7

quote:

3 NOTE SLANTS

Welcome to the world of approximations. You ain't gonna get many of these in perfect tune no matter what guitar scale or string spacing you have. JB's specs for the JB Frypan were designed to give as much accuracy as possible to all the 3 note slants including those split string ones. (and he should know!!).

Lets look at the Am forward slant in the key of C :


E --- 5 --- ....... A ........ 6
C --- 4 --- ....... E ........ 3
A --- 3 --- ....... C ........ 1


The A note on string one is 2 cents FLAT of Fret 5.

The E note on string two is 14 cents FLAT of Fret 4.

The C note on string three is 16 cents SHARP of Fret 3.

NO WONDER THIS ONE IS A BEAR!!!




Please don't flame me ... this is just the way it is ...

This example is based on the root note "C" being tuned "straight up" (relative to A-440) ... but it doesn't matter.

If your "E" is tuned straight up ... or your root (C) is situated 5-10 cents sharp (to "fit in better with ET instruments) ...

The geometry remains constant ... certain notes in certain slant positions will simply not "line up" ...

Thats what happens when you use an ET Fretboard on a JI-tuned instrument.

I hear some of ya ... so tune ET ...

Ok ... now even your 2 note ... straight bar harmonies are "approximations" ...

As usual, just tryin' to help ...


The appropriate "mathematical deviations" are given at the bottom of that essay ... based on the root C

I have a 30" scale on my baritone weissenborn and don't find #3 note slants a problem at all. I think its what your used to. I've always played a longer scaled instrument and to be honest I find the scale length on my ricky T logo a little crowded.

On steel the frets are just a suggestion. Well, that's my excuse for shaky intonation anyway.

My present lapsteel here is 19.75 " scale.
Like a strat for midgets.
But fits in the back pack ok.
Tuned at the moment L-H, E F# A C# E G
Thinking an A7 /A6 / F#m7b9.
Bluesy and versatile so far.

I will entertain any tuning suggestions.
It does have some slants, but still getting used to this scale... VERY short.

There's always trade off's.

I have a 26" Stringmaster T8. In spite of being a 3 necker, it is fairly narrow. this means the strings are very close together.


Combined with the long scale,this can make some of the slants very "trying". The plus side is the margin of error on harmonics is much greater and you get much better harmonic sustain on harmonic slides.

Moving to my 22" Fender Dual Prof 8 takes a little adjustment as the shorter scale is combined with VERY wide string spacing.

Sometimes I just give up and spend most of the time on my D 10 pedal steel with the 24" scale, even using it for a lot of non-pedal stuff. Although it sometimes draws strange looks from folks seeing all the slants and very little pedal pushing.
