What vibrates in a recorder to make sound?

Answer 1

the mouth piece is the part of a recorder that vibrates

Answer 2

The recorder makes a very simple tone, relatively free of overtones. It is similar to a Flute but less "breathy" or "windy" in the low register, and less sharp in the higher register.It is best to learn about the timbre of the recorder by listening to it, or, better yet, playing one yourself.

Answer 3

The Part of the air inside the recorder vibrates . It's a little hard to picture this if you only think of a vibrating string, because it's not quite the same.

The air in any container is able to vibrate through waves of pressure. When you blow into any container you momentarily compress the air (you're squeezing more into it). When you hold your fingers over openings in that container you are providing resistance to the pressure and when you release your fingers over openings, you are releasing the resistance and allowing escape of air. By experimentation, scientists have observed that if you start a wave of air pressure in a container, it bounces back and forth from end to end with a frequency that depends on the length of the container. The overall volume of the container will affect the "tone" or resonance. An opening will let you hear that wave or note. Your blowing starts the wave with compression of the air.

Fingers placed over finger holes in a recorder do two things: they confine the air to a certain part of the tube of air AND they effectively change the "resonant" frequency by preventing the air from escaping at a point nearer your mouth. Recorders are designed so that if all holes are closed, the air escapes at the end with a note dependent on the length and size of the hollow part. The more air you force to vibrate, the lower the frequency of the "wave" and the note that you hear. This corresponds to strings on stringed instruments, in that the heavier ones vibrate with a lower frequency or lower "note". (You should remember this principle for the future, when you're playing with wine glasses filled with water or other instruments that are new to you.)

Blowing harder does not affect the amount of air that vibrates, only the strength ("amplitude") of the wave. So, if the instrument design allows it, the note may be louder.

Usually your finger pattern over the holes will cause one note to come out of the instrument, but partially covering holes can cause more than one vibration to be produced and released, so you get mixed notes.

By experimentation, makers of recorders and similar instruments determine what notes they WANT to produce, and put a finger hole in the right place for each note.

Answer 4

The mouthpiece vibrates if it is moist. When you blow air, it passes under the mouthpiece and forces it down. Then up, then down. This produces a fuzzy note, that you can adapt by blocking the holes in the rest of the recorder.

Answer 5

The speaker vibrates and moves the air. Electric current creates a magnetic field which deflects the cone from it's quiescent position causing the air to move. That air moves your eardrum and does the same thing basically.

Answer 6

The sound on the recorder is produced by the labium, located on the fipple of the instrument. Air directed by the mouthpiece hits the labium and is "split in two," thus creating the tone. This tone is manipulated through the rest of the instrument.

Answer 7

a recorder does not have a reed, so there is nothing physically vibrating (unlike a Saxophone), it works as more of a whistle whose pitch you can affect by covering the various holes

Answer 8

The mouth piece vibrates when you play a recorder

Answer 9

because it is smells like poo
