Red Brass Also known as Rose brass, this has the highest copper content at around 90%. It gives a warmer and mellower tone but doesn't project as well as alloys with higher zinc content as it is a softer metal. It is often used for the leadpipe (the main tube nearest to the mouthpiece) of student instruments as it helps to prevent 'red rot', a corrosion caused by the build up of acidic dirt / saliva inside the tubing. Manufacturers vary in their choice with some using the same brass alloy for an entire instrument and others changing it for certain components. The main place for a different type of brass to be used is typically the 'bell' section as this has by far the most influence on the overall sound produced. The leadpipe of an instrument also occasionally has a different brass from the main body of the instrument. That's for discussion on another day though! You will sometimes see other components manufactured in different materials, sometimes nickel silver is used on trombone slide legs or tuning slides and there are even instruments with sterling silver bells. I hope this brief look at brass alloys though will help you understand that particular component of instrument manufacture.Do you want to work at a glamorous bench like this? There are many other factors that influence the sound of the instrument, from bore size and bell flair to the thickness of brass used. So how do I find someone willing to teach me repair?įirst, you’ll need to find someone that does repairs in your area. That’s a no-brainer right? Well, it’s easier said than done. Like I’ve said previously, there aren’t many instrument repair people in the first place… and just because a music store sells horns, doesn’t mean they fix them in house. If you don’t know a repairman yet, go online and find one. It shouldn’t be too hard to find a repairman in your area using Google. Check out their website and you can probably find their contact info.
