That's not the correct way to use it.
A slide...and their lips.
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.
Your not suppose to put the microphone on the trombone you are suppose to put it in front of it trust me I have smart music.
trumpet, French horn, trombone, and the tuba.
the slide can extend to produce a lower pitch, and it can also retract to produce higher pitches. all brass instruments can also produce different notes by tensing up the lips (higher notes) or by relaxing the lips (lower notes).
Your lips are what vibrate when playing a trombone.
The trombone produces it sound by players buzzing their lips
The player's lips vibrate.

they are all brass instruments but all have different pitches and different embouchures, such as the tuba is the lowest brass instrument and the trumpet is the highest and the trombone and french horn is in the middle, a tuba you have to have big lips to vibrate them loose and trombone and french horn too but you have to have tight lips for them and trumpet you have to have small lips and they all have valves except the trombone which has a slide to change pitch which makes it harder. (sorry if this was not the answer you wanted because i am a trombone player).
To play the trombone you press your lips together tightly and blow this creates a buzzing noise you do this into the mouthpiece.There ar seven positions on your slide.the tighter your lips the higher the note the loser your lips the lower the note. Keep trying its hard at first but then its EASY.

It changes by th embochure of your lips and the position that your slide is in. :)
like you're kissing someone and make a rasberry sound

Yes, a trombone is a brass musical instrument. Like all brass instruments, sound is produced by the vibration of the player's lips in the mouthpiece.
try cream which comes on milk & rub it on ur lips
