Hello, Rich35.
One person's opinion:
You have a valid request for a Altered Harmonicas Fan Club. But,
altered harmonicas are usually either diatonic or chromatic harps.
They already have locations at SlideMeister.
Here are 4 valuable, FREE web sites for an in-depth listing of altered-tuning
and experimental reed placements harmonicas, chromatics and diatonics:
www.patmissin.com (a listing, and some discussion by Pat Missin)
https://www.scribd.com/document/111434406/Anthoogy-of-Harmonica-Tuning(compiled by Eugene Ivanov, uses Missin's site as a reference, plenty of discussion
by Eugene). This 69-page book is freely downloadable, in Scribd's 30-day free trial.
www.seydelusa.com (look for the Harp Configurator section, you customize your own reed placement,
to be custom-made by Seydel).
www.leeoskar.com (Lee Oskar harps are diatonic, single reed, standard production, not experimental,
but Lee has clear descriptions of major key harps; 2 types of minor key harps; and
1 altered major key harp reed placement).
Thanks, Rich, for your request. We may discuss altered tunings of diatonics here
under your title: Melody Maker, and Other Altered Tunings. For chromatic harps,
we may discuss them in the chromatic harps sections.
Some altered tuning diatonic harps are listed by Ivanov and Missin as tremolo harps, octave
harps, harmony harps (Hohner Johnny and Seydel Hochlandsklange are discontinued) and
other double reed (per note) diatonic harmonicas. We are free to discuss experimental tuning
diatonic harps here, under your descriptive title.
Thanks for the opportunity.
Best Regards
