Hi was just watching a vid from @davidkachalon in the tongue blocking technique section on Super Vamping. I have heard the term Vamping as a guitarist I’ve vamped a rhythm out on chords. But I never heard of super vamping. U- blocking is another term I am unfamiliar with. For ages I couldn’t figure out what the difference was between what I know now to be a trill and what a vibrato was? I’ve been playing for 30 years and I pretty much made up my style as I went along copying different instruments for what I wanted never knowing what the hell the techniques were called, this could be a huge stumbling block for beginners or people like me who did not have the internet, etc when I was learning. what about a glossary of terms and techniques speaking of which does anyone know a book with these things in it? Again, might be a big help to have this knowledge
U blocking is making the toungue do a U shape. I dont recommend it. 
I would absolutely love for there to be a terminology dictionary. There are still many, many harmonica terms I don’t know because I self-taught. But we have to get this stuff written down.
I have great fear of the community (and broadly, much of humanity) losing knowledge as a result the de-emphasis on expertise over the last 20 years, and when that combines with the fact that AI will be writing the next incarnation of the internet, we are at great risk - nay, grave risk- for losing a metric ton of real collective knowledge.
We’ve already lost a metric ton of it in the harmoncia world. Think about the Windy City Harmonica club, which used to regularly have over 200 people attending - that group would have housed incredible amounts of collective knowledge. But the world changed, and people stopped going.
And where did that collective knowledge go? Much of it not archived anywhere. Thank god for people like Joe Filisko, who actually write that stuff down, and Bill Morris, who is going to a blues harp club monthly to showcase orchestral harmonica music.
Another notable example is AJ Windmeyer, AKA The Harmonica Archivist, who has an enormous collection of harmonicas as is a reference for the Hohner museum in Germany.
We need to start getting this stuff down in books and online before it gets lost to technology, the drivers of capitalism (e.g., only saleable books are published), and simply people getting older and passing away.
Getting serious about this over the next 5 years is probably more important than people realize.
I agree a lot of old players have probably forgotten more stuff than I’ll ever know and they’re no longer with us.
Another thing that just occurred to me, there are some people out there who think only blues can be played on harmonica, I met a young lad last week who thought that. I texted him a list of other great players who are not just blues
@Hogie.Harmonica It’s not just harmonicas that suffer, before doing a career change my last year at sea was as a training captain and 90% of classroom trained junior officers didn’t know how to pick up, let alone use a sextant. Morse and semaphore skills are no longer taught. Fortunately the harmonica hasn’t been relegated to computer generated YET!

Yep it’s all great, until the tech dies on you, then you’re up a certain creek without a paddle.
@Andy2 Only if you can find the right creek in the first place
