Hi all, I'm fifteen and I am the principle trombonist in the Tucson Philharmonia Youth Orchestra, and I study with Steve Gamble and Mike Becker, the latter who often freelances with the Chicago Symphony, and for all you string players, recently had a two week long stint with Yo-Yo Ma and his Silk Road Project. I have been playing the trombone for three years and am preparing to audition for a conservatory (Julliard, Curtis, etc.). Since I often practice upwards of 4 hours a day often for more than two hours at a stretch I happen to have acquired Satchmo syndrome, also known as orbicularus dehisence, or the fraying and herniation of the orbicularis muscle in my lip. Surgery is an option, and while searching for a surgeon who will do this procedure (and do it well ) I have decided that just in case I don't have this procedure done and for the betterment of the musician in me, I will take up a new instrument. I have already decided and have rented out my instrument of choice and it is the double bass, one because cellists are a dime a dozen, violin is too flitty, and the viola just plain sucks, and number two I come from an instrument that is very versatile, and the bass is just as versatile. My main question for you today is the tone quality one can achieve on the bass. I am and always will be a brass player, and to me, everything is about the music, the music being second only to tone. I know there are things sound depend on, i.e., the instrument, strings, etc., but aside from all this is there a specfic technique for achieving a good tone on double bass (pardon my stupidity). For instance for brass it involves lots of air (genetics and the shape of the mouth and a good ear matter too) and a wide open space in the mouth (there actually is no real written in stone way to get a good tone, certain things are just understood and the player uses his ear from there). Once again, if in the midst of my babbling you've lost sight of the question: Does tone play an important role in the world of the double bass or do you just draw the bow across the string and get whatever comes out? I know all is not that simple, but I couldn't help but wonder if good tone is very sought after and practiced in bassland, and if so how does one go about it? Thanks in advance for your replies.
