The recent thread about using more than one key of solo tuned chromatic (the approach I fell into) made me think about the advantages to symmetrical tunings that offer all keys with just a few playing patterns, unlike solo and bebop tuned chromatics that require different patterns for each major scale (except C and C#).
I learned chromatic as a kid with a key of G chromatic like the one my great uncle played for family sing-a-longs. G is a good key for sing-a-longs and G chromatics have been available for a long time. His was the first harmonica I ever heard played in person, in 1960 or '61. So I asked for and got a solo tuned chromatic and the solo tuned interval pattern became hardwired into my brain between the ages of 11 and 21 as I figured out how to play different melodies on it. I only played in a few keys when I switched to diatonic for rock and blues. I still only play in a few keys now after resuming chromatic.
After I resumed chromatic in the 1990s in order to enhance my musical options, I picked up where I left off. I just had a G and C solo tuned chromatic until I fell in with people playing lots of jazz in keys I was unable to play. To keep up I added other keys of inexpensive Hering chromatics as a fast way to play in many keys without the steep learning curve required to do it all on a C solo tuned chromatic. The gig money from playing out payed for the different keys, and I could write them off at tax time.
So why do chromatic players still advocate solo tuned or bebop tuned instruments to beginners? Why do we keep trying to crash through the brick wall of awkward keys in this layout when we could open a door and walk through without bruises by using a symmetrical note pattern tuned instrument?
If I had begun with a diminished (or augmented) and had THOSE patterns hardwired into my brain I could play in all keys on one instrument. My instrument case would be considerably lighter. My financial investment in instruments would have been much lower.
I think I am beyond switching over to a symmetrical tuning due to my long term habituation to the solo tuned interval pattern (though bebop would probably not be too big a change for me).
But why don't chromatic harmonica advocates
including SPAH strongly advocate for new players to learn chromatic harmonica on an instrument with a symmetrical note pattern? The idea of learning a few patterns that would allow me to play all keys is enticing.
Here is a link to a site describing diminished tuned chromatics. Reading it made me wonder why solo tuned chromatics are still prevalent.
http://www.angelfire.com/music/harmonica/dimichromintro.htmlThere are other sites giving info on diminished, too. Try a search for "diminished tuned chromatic harmonica".
I don't see myself stopping what is working for me now, but I would like to hear if there are reasons to continue solo tuned chromatics other than, "That is what I learned on."
