I figured I'd drop something a bit different into the mix of threads mostly related to ebay finds of vintage horns, and ask a question: Is it possible for someone, with today's tools and technology, to effectively teach themselves to play trumpet? Often times the very first suggestion thrown out when someone posts a question regarding technique, chops, etc, is "get a teacher," or "ask your teacher," or some other similar sentiment. This has caused me to ponder whether or not one can effectively teach themselves in large part to be an effective trumpet player, and especially in light of the tools that we have thanks to technology. I'm a DIY kind of guy, and I teach myself how to do a lot of things. I wanted to lay a laminate floor in my foyer and kitchen. I didn't take lessons on how to lay a laminate floor - I did some reading and research online, and then just did it. Did I make some mistakes? Yeah - looking back, there were some things I did early in the project that I could have done better, and I was doing better by the end of the project because I observed what needed to be done differently or better, and then I made the corrections on my own - I didn't need a teacher to tell me what was already plainly apparent. If I'm missing the boat completely on this, please feel free to chime in, but for the most part the role of a teacher for a trumpet student is to observe, listen, correct, and prescribe practice that will refine and improve the player based on the knowledge they have garnered in their own years as a player, and often repeating lessons of the teachers they had. All things considered, things like scales, keys, note values, music markings, etc, are all academic - they can be learned via Google on the internet, but could a player not make good use of audio and video recording via computer technology to objectively observe themselves to refine and correct deficiencies in their own playing? Discuss!
