Marketing v Application?
I originally posted this in the "Gear" Forum but it was suggested by another recognized contributor that I get your feedback which I absolutely agree with. I / We , would like to get your input to the following.
Interesting. I just purchased a Rocket Low C which I like. The Hohner packaging that it came in, i.e. the underside of the box identifies Progressive for Country, Pop, jazz. Marine band is mostly Blues. MS-Series blues, pop, and Country, and then the Enthusiast which is a mix. Is this purely marketing? Progressive is not Blues Application?
Usually the temperament for a model doesn't change for different keys or low-vs-high.
Hohner does this dumb sorting perhaps simply as a way of helping a new harmonica buyer to make a decision. In fact you can play any of these styles with any of these models.
EXCEPT - that the temperament, the fine tuning of the notes in the scale, does differ slightly among model classes. But the new player, and even the intermediate player, is unlikely to notice these nuances. If you do notice them and prefer a model that is tempered slightly differently and care enough about it, you can always learn to fine tune, so that if that Low C is only available in a Rocket and you want it to have the fine tuning of a classic Marine Band (which is actually different from all of the presently available temperaments, in something called 7-limit Just) you can modify it to that.
