The following note is on the Seydel web site on the "details" page for the NonSlider Chromatic:
We are overwhelmed by the great interest for our NONSLIDER Chromatic project study. The first edition was sold out within hours. You can still order and reserve it. All new orders will be delivered at the end of July from your local SEYDEL SALES partner or from the factory directly.
We are happy to inform you as soon as the instrument is back in stock. Please let us know your interest by email to info@seydel1847.com.
Hmmm. . . the first batch was sold out within hours. I must not be the only harmonica enthusiast attracted to the idea of NO SLIDER and NO WINDSAVERS!
Caveat emptor!
No offense intended toward anyone in what follows. However. . .
I get the attachment to familiar things. We spend an enormous amount of effort and time learning how to make music on whatever we can get at the time. Nobody wants to throw all that effort and time away and start over. Nobody wants to throw away all of the instructional materials and beautiful performances either.
I am reminded (regarding the slide chromatic AND the diabolic harmonica) of that old Russian proverb:
"The marvel is not that the bear dances well, but that the bear dances at all."
There are a few of us who are willing to look for something DIFFERENT (which does NOT always turn out to be something BETTER) that will enable us to play as we want to play without as much effort. My foray into alternate tunings on diabolics was driven by that desire. I didn't like the fact that the lower octave was "missing" 2 notes and the upper octave was "missing" one note, with only the middle octave having all 7 notes in the diabolic scale. Additionally, I didn't like the fact that there were only TWO real chords (triads) on it - the tonic chord (all the way across the 10 blow holes) and the 5th chord (only in one place on the draw holes).
While studying Steve Baker's Harp Handbook, I found the discussion of alternate tunings, including the Spiral (Seydel's Zirkular or Circular) Tuning. SERENDIPITY!, as the Geico gecko says. NO missing notes (but only a 2.5 octave range) AND real chords starting on every scale degree AND (as a result of having all the notes) modal scales as well, especially Mixolydian and Aeolian (natural minor).
Why were (and still are) those things important to ME?
Because the genres of music I like (bluegrass, country, folk, gospel) are so much easier to play using this alternate tuning. I don't have to work my tush off trying to figure out bending and overbending (although I did learn how to do that prior to finding the Spiral Tuning explanation and Seydel's Harp Configurator).
For those who like their "standard" chromatic designs with slides and windsavers, you can keep your "standard" chromatics with the associated problems. I am reasonably confident that this NonSlider Chromatic will NOT overcome the inertia of the harmonica world and cause the Slide chromatics to disappear.
