Saxophones and oboes are conical, and behave like closed conical pipes. They are closed at the reed, just like the clarinet. Flutes are cylindrical, and behave like open cylindrical pipes. The sound is made by blowing across the opening at the head joint, and it is not closed like in other woodwinds.

How does a saxophone work physics?
In making a sound on the saxophone, one blows air at a high pressure through the mouthpiece. The reed controls the air flow through the instrument and acts like an oscillating valve. The reed, in cooperation with the resonances in the air in the instrument, produces an oscillating component of both flow and pressure.
How does the saxophone create sound waves?
The sound of a saxophone is generated by vibrating the reed attached to the mouthpiece, which the player puts in his mouth. Instruments that make sound in this way are called reed instruments.
What type of instrument is a soprano saxophone?
The soprano saxophone is a higher-register variety of the saxophone, a woodwind instrument invented in the 1840s. The soprano is the third-smallest member of the saxophone family, which consists (from smallest to largest) of the soprillo, sopranino, soprano, alto, tenor, baritone, bass, contrabass saxophone and tubax.
How do you tell if a pipe is open or closed physics?
What is open pipe in physics?
An open ended instrument has both ends open to the air. An example would be an instrument like a trumpet. You blow in through one end and the sound comes out the other end of the pipe. The keys on the trumpet allow the air to move through the “pipe” in different ways so that different notes can be played.
What wave is saxophone?
The sound of the saxophone is a little like a sine wave when played softly, but successively less like it as it is played louder. To make a repeated or periodic wave that is not a simple sine wave, one can add sine waves from the harmonic series.
How does a saxophone change pitch?
A larger volume vibrates more slowly, for lower pitch; a smaller volume vibrates more quickly, for a higher pitch. For most woodwinds, the player changes pitch by opening and closing holes along the instrument’s length. Closing more holes makes the instrument longer, making the notes lower.
How does a saxophone produce different notes?
Each note on the saxophone is created by opening and closing a series of tone holes that produce different natural frequencies of the oscillating air. The lowest note of the instrument is played by closing all of these tone holes.
How would you describe the sound of a saxophone?
The saxophone sound is generally described as powerful yet mellow, round yet complex, and versatile across many genres, including classical, jazz, pop, and rock. In technical terms, on its softer end, it’s similar to a sine wave, but this similarity lessens when played louder.
What frequency is a saxophone?
The values of fb for the tenor and the alto saxophones are 618 and 837 Hz. These lie about a semitone below the break frequencies that would be calculated for such transposing instruments on the basis of the 1500‐Hz fc that belongs to essentially all of the nontransposing soprano instruments.
What is unique about the saxophone?
It Has a Unique History The saxophone is the only instrument in wide use today that was invented by a single individual — a musical instrument designer named Adolphe Sax, hence the name saxophone. Sax was born in Belgium in 1814.
How is the soprano saxophone made?
The soprano saxophone is basically a conical tube that is constructed in two sections, the neck and the body, with a single-reed mouthpiece attached to its narrow end. Made from drawn brass, the tube is straight with a slightly flaring bell.
What type of instrument is a saxophone?
What is the role of the saxophone? Though the saxophone is made of metal, it generates sound with a single reed, and so it is classified as a woodwind rather than as a brass instrument.
What is the difference between soprano and tenor saxophone?
What instruments are open pipes?
The most well-known applications of the concepts you’ve learned about are musical instruments, particularly woodwind instruments like the clarinet, flute and the saxophone. The flute is an example of an open pipe instrument, and so it produces standing waves and resonance when there is an antinode at both ends.
Is a trumpet an open or closed pipe?
Because the lips impose a pressure antinode at one end of the tube and the other end is open to the atmosphere, the trumpet is an open-closed pipe. Therefore, considering just the cylindrical tubing of the instrument, the wavelength of the fundamental resonance is four times the length of the pipe.
What is the difference between an open and closed pipe?
Open and closed ends reflect waves differently. The closed end of a tube is an antinode in the pressure (or a node in the longitudinal displacement). The open end of a tube is approximately a node in the pressure (or an antinode in the longitudinal displacement).
Is a violin open or closed pipe?
Answers and Replies. I take it you are happy with stringed instruments. They are clearly all “closed” at both ends. This means the standing wave pattern has a node at both ends, and the fundamental frequency has a wavelength twice the length of the string.
Is a clarinet an open or closed pipe?
The clarinet (right) is a roughly cylindrical instrument which is open to the outside air at the bell, but closed by the mouthpiece, reed and the player’s mouth at the other end*.
Where does the air come out of a saxophone?
The bell of the saxophone serves to radiate the waves out into standing air. The more the waves are radiated out, the less the waves are reflected inside the bore, and the instrument projects more.
What key is saxophone in?
Tenor and soprano saxophones are in the key of B♭, just like clarinets. All three of these instruments produce a B♭ when playing a C on the score. That is why in order to produce the same C pitch as keyed instruments or the flute (concert or “written” C), they must actually play a D.
What are the parts of a saxophone called?
Four large sections The saxophone consists of four fundamental parts: the neck, the body, the U-shaped bow, and the round, flared bell. Along the length of the instrument, there are 25 tone holes.
What is the tuning note for soprano sax?
Using a good tuner (at A = 440 hz reference), tune the soprano’s middle C to concert Bb. Mark the cork lightly with a pencil. Remove the mouthpiece and recheck the embouchure tension by blowing the concert Db. Replace the mouthpiece on the cork and check the middle C tuning note again.
Why does my alto sax sound flat?
A saxophone is likely to play flat notes if the mouthpiece is not correctly pushed further down the cork. Thus, the air column gets longer when you try to blow into the saxophone and renders lower notes than usual. Using grease on the cork and pushing the mouthpiece towards the neck should fix this.
