The Structure of the Saxophone
[Experiment2]What happens when the length of the instrument changes?
Performing a sound experiment
In the next experiment, we changed the length of the tube.
* This recording was made during the experiment so the actual tone might be different.
The longer the tube, the lower the sound that emerged. Whether cylindrical tubes such as the recorder or tapered tubes such as those used in this experiment, they behave in the same manner: the longer they are, the lower the sound that they produce.
In this experiment, as the length increased, the amount of breath required to make a sound also increased, making it very difficult to play.
The note became higher and higher as the taper increased. With conical tubes of the same length, the higher the degree of taper, the higher and brighter the sound.
However, as the taper increased, the more difficult it became to maintain a sound at the same pitch. Of the three tapers used in this experiment, the smallest taper is the same as that of the soprano saxophone. The largest taper was larger than that of any saxophone.
Originally, a mouthpiece with a volume appropriate to the tube was used to make it easier to play. If we bent the end of this paper, the sound would probably be better. If we then skillfully opened some tone holes, we could make a musical scale and enjoy some music.
