Chromatic with Offset Tonics (COT) as applied to PowerChromatic

Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!

Chromatic with Offset Tonics (COT) as applied to PowerChromatic

Post by IaNerd » Sun May 22, 2022 4:11 pm

I offer this discussion even though I am not sure if the idea is useful. This Forum’s many experienced and insightful members might see possibilities that I am missing.

I feel compelled to share this idea because I am surprised and intrigued by what I found when I applied my Chromatic with Offset Tonics (COT) concept (at viewtopic.php?f=9&t=874#p3904 ) to Brendan Power’s own PowerChromatic tuning.

We see (below) that in the slide-in layer, the breath pattern is reversed for all the diatonic scale degrees except the tonic. This layer has the exact format of a well-known chromatic tuning called ”Classical”. While the PowerChromatic layer gives us draw-bends for four notes of the scale, the Classical layer gives only two.

Another way to look at it would be as Minor Solo Tuning in D

Hmm, I'm not seeing that. But what you say helps me to see the slide-out layer as Dorian (which is minor) Classical tuning in D.

It would be starting on hole #2:

DE FG AB CD DC

But you're right: because the doubled D notes are different breath, it's not the same as the Solo pattern *where doubled C notes are blow).

I am more surprised than I should be -- and strangely delighted -- that this works both ways ....
