For playing E don't press down any valves. For low E press down the 1 and 2 valves. 😃

The trumpet one of the oldest musical instruments, belongs to the brass family. It is played by blowing air through closed lips into the mouth piece creating a buzzing sound that creates a standing wave vibration in the inside column. The trumpet has 3 piston valves with holes in them called bores. When you press a valve down it redirects the length of the airflow path, allowing different notes to be played. The pitch of a note can be altered by using the tuning slide.
This process is called compaction.
:D
Idiocy
the actual part that you put your fingers on are called the valve or finger buttons. The entire piece that moves up and down is the piston or valve.
first valve down
It's called "Taps". PS you can play all the bugle tunes with first and third valve held down.
compaction
they are called chemical elements.
