Re: “CoG CuD” Neck Rack Tuning for 10-hole harp

Please note that the major triads in the blow row align perfectly with those in the draw row. This makes for optimally fast and easy chugging between those chord pairs. The same is true of all the b7th tetrads. This tuning is also sports a number of triple-stop octave pairs, especially in the blow r...

Re: “CoG CuD” Neck Rack Tuning for 10-hole harp

When using a three-hole embouchure, this tuning has only one "sour zone". Playing 4-5-6 draw would sound bad.

Contrast this with tunings that have multiple such "sour zones".

Re: “CoG CuD” Neck Rack Tuning for 10-hole harp

I'm also seeing now that this basic tuning, in a 13-hole format, could sport a very nice double/repeated Richter octave a la SBS and Lucky 13.

This would not, however, result in an additional blues scale octave, because the extended area would be missing the B-flat.

Re: “CoG CuD” Neck Rack Tuning for 10-hole harp

I just noticed that if the partial Cmaj chord was extended for one more channel, then the minor hexatonic blues scale could be played for two complete octaves which have identical breath patterns . This seems almost paradoxical, because those two blues octaves span two different chordal areas of the...

Re: “Cumin Bob CoG” tuning for 10-hole harp

I've got one of these in hand now and have played it a very short while. My initial impression is that I perhaps should have carried the pattern of chambers 1-7 all the way to chamber 10. In other words, Cumin Bob sans CoG. I'm starting to think that my own go-to setup for blues/pop/rock would be tw...

Re: Spreadsheet for calculating chord frequencies *REVISED*

Clearly, our auditory system can distinguish and appreciate polyphony that is built on certain ratios of integers. Karl said: "Also, the ratio from the major 3rd to our subminor 7th is 7/5 = 1.4, which is the simplest (and therefore the smoothest sounding) ratio for the infamous tritonus, "the devil...

Re: Spreadsheet for calculating chord frequencies *REVISED*

One way to read the table posted by Karl: In ET, the major third would be 400 cents (or 4 semitones) above the tonic (zero). But in JI, it is only 386 cents above the tonic; therefore, 14 cents flatter, or "offset" by -14 cents. A "compromise" tuning might flatten a major third only half that amount...

"Cumin Bob” tuning for 10-hole harp

NAME: “Cumin Bob” tuning for 10-hole harp BASIC CONCEPT: This tuning is designed especially for single-note and octave-split play. I think it would be especially powerful if set up as low possible. In this example, which is intended for play in the key of G major, the pattern is to have a Bb major ...
