Thank you Kevin for starting this thread!
Although I can follow the reasoning behind it, I’m not sure a “superstar” melodica player would change much: in my experience, people tend to classify excellent players under the “virtuoso” category, like it’s just a matter of talent and not so much of hard work/quality of the instrument in itself.
I’m currently involved in the publishing of some didactic textbooks (mainly for my local students) so a question raises naturally in my mind: what about specific methods and/or technical materials for the melodica? There’s not much around, afaik… Do you think that is an issue in the perception of the instrument?
