It lowers the pitch of the sound produced. For more information please see the wikipedia article about trombones.
A trombone is typically made from brass, specifically a mix of copper and zinc known as brass alloy. The outer surface is often coated with lacquer to provide protection and maintain its appearance. The inner tubing is carefully constructed to produce a resonant sound when air is blown through it.
Lowering the frequency of a wave on a string will result in a longer wavelength and a lower pitch sound.
When sound dies away, the sound energy is gradually transformed into other forms of energy, such as heat energy due to friction between molecules in the medium through which the sound waves passed. Eventually, the sound energy dissipates and is no longer detectable as sound.
A musical sound produced by blowing air through the lips is called a "buzzing" sound. It is commonly used in brass instruments like the trumpet or trombone to create sound.
As sound moves away from you, the wavelength stays the same but the frequency decreases, causing the pitch to sound lower. This is because sound waves spread out as they travel and the distance between wave peaks increases, resulting in a longer wavelength.
The trumpet in general is a higher pitched instrument because it is smaller and has less tubing.
the trombone is longer than the bugle, giving the sound a longer path to travel, thus making the sound waves more spread out, giving it a lower tone.
I'm not 100% possitive, but I think its called a Slide.
The trombone produces it sound by players buzzing their lips
The purpose of valves in other brass instruments is to alter the length and shape of the tubing that vibrations from lip buzzing travel through, which in turn alters the sound that comes out. Extending and shortening the slide on a trombone has the same effect.
Both the slide on a Trombone and the valves on a Trumpet are to play all of the different notes. (ie: press the 2 and 3rd valve on a trumpet to play G#). music is sound, sound is compsed of "waves" or the peaks and valleys thesound travels, looks like a wave. The longer the distance between the peak and valley, the lower the note/pitch. the shorter the distance the higher the pitch. This is best seen if you pluck a guitar string. You can see the string vibrate to the sound wave. Shorten the lengthen of the string and you produce a high pitch. The slide and vavles do this in the trumpet and trombone. Pressing the valves re-channels or directs the sound wave produce by the player's lips through shorter or longer tubing/distance. The trombone this is done by moving the slide up or down.
The pitch is changed on a Trombone by moving the slide or changing your ombisture.
He or she plays the Trombone, a musical instrument of the Brass family. Trombonists can play in an orchestra and/or band, and can also be used as a solo instrument. The trombonist reads music or plays songs by ear on the slide or valve trombone.
The trombone is shaped like that so it can produce a fuller and louder sound. :)
carefully with a blowing sensation
thats where the sound comes out.
A very short explanation is, you vibrate your lips while blow air through the mouthpiece. Pushing valves changes the length of tubing that has air going through it, causing different notes to sound.
