Thanks for that Vulgano, Dr.Mark, I was not questioning my teacher simply because the sound he gets is a sound I would love to emulate as it was so 'clear'. I was just trying to understand from an educational point why Greg Spence made it out (to how I understood it anyway), that 'most people play wrong' because most people 'buzz' on the mouthpiece which 'defeats the purpose' of the design of the 'mouthpiece receiver' which is supposed to cause the mouth to buzz and thus you buzzing = too tight. This idea sounded very controversial to me because that is basically saying 'everything trumpet players learned in the last 1000 years is wrong, I have a better suggestion of how trumpet actually should be taught, so be careful if your teacher is also stuck in the wrong way of thinking and thus teaching you to be another player that plays wrong" That is the idea I received from his video. Perhaps I misunderstood, but that is what I left with after watching them (prior to having a real teacher - one in person - ) So when I was in the lesson, told to buzz, I couldn't buzz, yet I know if I Plugged it into the trumpet it would buzz. However it made sense at the same time, by allowing that, I am actually allowing the trumpet to control me as I am reliant on the MP being in the trumpet before my lips buzz instead of Buzzing the exact note I want then putting it into the trumpet and knowing that is the note I will get and allowing the trumpet to amplify what I am actually doing. Thus I am telling the trumpet what to do, not "blow air" (greg spence) and then let the trumpet tell me 'ok you will buzz now' once I put MP into the receiver. Which again to me sounds like trumpet telling you not you telling the trumpet. Anyways I looked at some stuff so far, had a nice close view of Wynton Marsalis warming up, I had a listen to Chris Botti etc. It seems to me Marsalis also has the DIM shape lip. His lips in relaxed position are all stuck out (similar to mine) yet while he is playing I noticed him holding them 'rolled in' in comparison to his relaxed position, or better said, in the DIM position. Even when he breaths I can see him open the mouth but retain the DIM position so his lips dont fall back into the 'out' position. My teacher said to do DIM... I just saw someone very obviously doing that who is world class. To me this was important because the whole 'blow candles out' idea that I received off the net (to not be too tight, buzz etc), never gave me the DIM position and this is the very first thing my teacher picked on. He told me my lips are pushing into the mouthpiece like a horse. Eeek. Chris Botti mentioned buzzing as important. Was a short segment, but "like blowing into the air but through a tube you have to buzz the lips at the same time" Which again, as my teacher said "buzz through the mouthpiece" makes sense again considering 2 players here mentioned do the DIM and the Buzz and both world renowned. So that just tells me "what the hell is Greg Spence on about then" making it out as though everyone is wrong, or at least, leaving that impression that doing that is wrong, which then would state marsalis and Botti play wrong since they do it the traditional way so to speak that I am being taught right now. Breke - was not questioning my teacher as explained. Questioning why Greg Spence left to interpretation (like myself before I got a real teacher) for people to THINK that buzzing is wrong when the world's best do that. I am just looking at it from the point of view from where I came from. I tried to learn online, due to time, money, distance etc, and there may be many many other people trying to do the same. They also can find Greg Spence videos, and they also can leave with the impression that majority of trumpet players were taught wrong because they buzz. It can also therefor colour the way people think about trumpet playing and having a mindset that 'the traditional way' is the 'false way' and thus be convinced and in their belief system that all other ways are actually wrong. This is what I am questioning. If I had done this online stuff and thought "Greg spence was not saying buzzing is wrong, he just has another idea" would not be an issue. But I left with the impression he was flat out saying 'everyone is wrong, buzzing is wrong, you need to change the way you think, this is how it really should be'. So think about how many people that perhaps for whatever reason cant get a real teacher, sit there listening to that and if they are programed to believe "hey everyone IS actually playing wrong" because they found these free online lessons (such as I did). Thankfully I have no problem changing, but some may. This is what is in question for me because to me, that says more evil than good will come out of that.
