Hi. Let's talk a little more about valved brass instruments and how they work. As you can see, this is not a tuba, and it is not a trumpet, or a euphonium, or a flugelhorn, or a french horn. It is, of course, the valved brass instruments' first cousin: the trombone. The two principles that we've talked about: the "longer the lower" and "you get what you give" also apply to the trombone.
So, to illustrate the principle of "you get what you give": If I buzz in 3 different notes, I will get out 3 different notes.
The other principle is "the longer, the lower". If I extend the slide, I make the trombone a little longer, so the pitch becomes lower.
The system of "the longer the lower" is a little easier to follow with the trombone: Every slide position is a halfstep lower than the previous. So: 1st position, 2nd position, 3rd, 4th, 5th, 6th, 7th. This corresponds to the fingerings on valved brass instruments of: open, 2nd valve, 1st valve, 1st and 2nd valve, 2nd and 3rd valve, 1st and 3rd valve, 1st, 2nd and 3rd valve.
There are also trombones that have valves: they're called valve trombone instead of slide trombones, and they are basically the same thing: just as the name says, they have valves instead of slides. There's also something called a "superbone", and it has both: a usable slide and valves.
Many trombones have one valve: It's called the trigger and it's operated with the left thumb, also known as the F-attachment. This trigger has the same function as the 4th valve on a tuba or a euphonium. Speaking of euphonium, if you can play euphonium, basically you can play the trombone: The range is the same, and the mouthpiece is the same. The only difference being that you use the slide instead of the valves to determine the pitch.
Now, what's so special about a trombone? Well, I'll tell you what's so special about a trombone! You can do that! You can glide between the notes. That's called a glissando.
But this can also, of course, be a disadvantage. Sometimes you might not want to glide between the notes. This is the secret: If you're playing trombone, you have to remember if you ever change slide positions you have to use your tongue to slightly articulate the new note. So, instead of this, you get this.
So, now you know a little more about the valved brass instruments' first cousin: the slide trombone.
hah he shaved! love this series.
