I think that I have finally figured this internet thing out! Thank you for being the inspiration to get me to seriously think about this!
We all google if we want to check something out. We get the info more or less easily and then move on. Playing trumpet involves another concept and I see a BIG discrepancy between googling and playing. I would almost say that a google state of mind is harmful to playing trumpet.
To learn to make music with a wind instrument - regardless if it is the human voice or a trumpet, habits have to be built. Habits are formed by endless repetition. That is exactly the opposite of getting one piece of pre-chewed information fast.
That fuzzy sound that you are talking about is the beginning of your chops starting to develop. The muscles are weak, the coordination is miserable and you have no experience to draw on.
You may have read here that we advocate long tones and slurs. We do so because that builds the habits, the muscle memory that makes the trumpet "sing". Learning to play is just like learning a foreign language. You learn single words first - the basic vocabulary, then basic verbs so that you can make sentences, then conjugation to express things over time. That is very analog to the trumpet: range, flexibility, articulation and dynamics. At the same time your brain has to feed those habits that you have built with the right things. That synchronizes when you have developed for a while.
So unlike google, even if you understand the problem and get a valid answer from the internet (which you are not in a position yet to determine), it does you ABSOLUTELY NO GOOD unless it turns into endless repetition and thus a habit.
We have players on the forum with libraries of music as big as the Library of Congress. That does NOT make them better players. Repetition does. The more varied stuff you play, the longer it takes to finely hone skills.
My advice is to only play the exercizes that your teacher gives you but then until they are MEMORIZED. Your playing develops faster, and your brain is free for additional observations!
