Short Introduction to Tremolo harmonica 

Hi Rod, tremolo is definitely an applicable term to be applied to a tremolo harmonica...

@@boystone Well, that's probably because traditionally everyone has called it that. I think the same has happened with the Fender Stratocaster Electric Guitar and its "whammy bar" or "tremolo system", which in reality is a "vibrato" device- the pitch bends down quickly as opposed to being articulated rapidly. The "tremolo harmonica" doesn't articulate the pitch rapidly; it plays pitches slightly off tune from each other simultaneously to produce that "beating" effect. This effect happens in vocal choirs- chorus effect-but it's not called "tremolo". Play vibrato, tremolo or chorus on a lute, for example. The techniques would be different. Do the same on the harmonica, especially on one that doesn't have polytonality like a Golden Melody (two Golden Melody harmonicas, one slightly out of tune for the chorus effect). In reality, I don't care what folks call the effect. They can call it "fiddy-fiddy", as long as everyone knows what effect they are after. We could even change the names of electric guitar pedals to: "wavy-wavy", "fiddy-fiddy" and "shimmer-shimmer", vibrato, tremolo and chorus, respectively. I had to voice my opinion, thanks. I enjoy your presentations!
