the vibrations from your lips
its your lips. Because you blow into it and it can be air!!
You buzz your lips, which causes the trumpet to vibrate. You change notes by pressing valves or blowing the air faster.
Trumpet partials are specific frequencies at which a trumpet can naturally vibrate and produce sound. Understanding and controlling these partials is crucial for a trumpet player to produce different notes and create a full range of musical tones.
The players lips vibrate, which creates the sound you hear. However, the sound vibrates, or resonates within the trumpet so it doesn't just sound like someone making farting noises with their trumpet.
An aerophone is defined as any musical instrument which produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes. So yes, a Trumpet is an aerophone.
It is because in order to play a brass instrument you need to vibrate your lips in order to play notes.
lips vibrate and this sound is passed through various pipe lengths to change frequencies
The musician places the mouthpiece against his lips. When he blows air through his lips, they vibrate. This vibration, combined with the air, is what creates the sound.
The way that the saxophone makes a noise is when the player puts their mouth on the mouthpiece, and the reed vibrates, sending waves of air through the saxophone, making a sound. The different pitches of the saxophone, or the different notes are determined when the saxophone player presses down fingering, therefor making the instrument shorter or longer. The way that the trumpet makes a noise is pretty much the same as the saxophone, only the players lips vibrate against the mouthpiece, instead of the reed. The trumpet player goes though different notes by moving the 3 valves, and loosening or tightening their lips. By pressing down the valves, the trumpet player makes different pathways throughout the trumpet. To make a higher sound, you have to tighten your lips, and to go lower, you have to loosen your lips.
A trumpet's sound is created by the player who uses his lips to vibrate the air he blows into the the horn. These vibrations resonate through the brass wall of the horn to form tones or notes. When the player depresses one or more of the trumpet's keys, the air column in the horn is changed, thus altering the pitch of the tones being produced.
The Trumpet its self doesn't vibrate, its the vibrations of your buzz that makes the sound. As you buzz on the mouth piece, the vibrations go through the horn to the valves. When it reaches the valves, according to the ones you have pressed down, it has to take different routs to get to the bell (This along with your lips, changes the note).
