Two parts of the reed open and close to produce sound waves. There is a slight difference between the bassoon and oboe. This difference is about reed. An oboe has a metal piece attached to the reed. However, the bassoon is entirely made up of the reed. To produce sound, the reed is inserted in the metal tube of the bocal. It is called a bocal and not a vocal because bocal is an indication that the instrument is basically a mouthpiece.
Like all the wind instruments, the most important part of its function is always present close to the mouth. Similarly, the reed of the bocal is the most essential part of the instrument. Talking about the sounds produced by the bocals, the high or low pitch depends on the blowing sensation in the instrument. Through the blowing sensations, a variety of pitch of sounds can be produced. It is easy to play the pianissimo, soft sounds, and gentle to produce timbre sounds.
Many musicians own various types of bocals to select and play a particular one that is perfect for them to play. The taper angle of the bocal differentiates between the timbre and the various types or bocals. The shape of the tube of the bocal is conical. The reed is inserted in the inner diameter of the tube to produce different pitches of sound. There are various types of bocals in this article, we will discuss and review the Bassoon Bocals.
The Fidget Bassoon Bocal is a 2 piece instrument. This instrument comes in its own casing as well. The mouthpiece of Bassoon Bocal is made up of crooked metal.
The two bocals are not of the same lengths. One is longer, and the other one is shorter in length. This is because the different lengths of the bocals provide different sounds as they can be tuned to produce high or low pitched sounds.
The tune can be changed by either adjusting the length or by adjusting the head joint and the barrel. The casing of the bocal is black in color that ensures to keep the instrument safe and secure from bending or breaking. The Fidget Bassoon Bocal has a crooked metal that ensures to provide a good grip to blow the instrument easily.
The Reed Bassoon Bocal is one of the most unique designs of bocal that produces a unique and delicate tone when blown. The tube is made up of nickel that is silver plated. However, the mouthpiece of the tube has a crook attached to it that ensures to provide a firm grip while blowing the instrument. One of the best things about the Reed Bassoon Bocal is that it is even professionally tested to add in more perfection in the structure and the sounds produce.
This element best satisfies while choosing the best type of bassoon bocal instrument. The pitch of the tones depends on the length of the instrument. The shorter crook is known as Number 1, and the longer crook is named as Number 2. Both the lengths ensure to provide a different pitch of tones according to their lengths. The Yibuy bocal is about This instrument is silver plated that gives a delicate appearance.
The Yibuy Bassoon Bocal is actually made up of copper that makes it highly durable and does not allow it to bend so easily. The mouthpiece of the instrument is also silver plated and has a cork attached to it. The cork makes sure to provide a firm grip to blow the instrument perfectly. As it is difficult to play high-pitched notes on the bassoon, bocals specifically for this purpose seem very popular.
When you buy a bassoon, two bocals of the same shape but of different lengths are generally provided. Usually when these two are included, the first, numbered "1," is the shorter and the second, numbered "2," is the longer. In Europe sometimes No. The preparation of a number of bocals of different lengths is for the sake of tuning, or precise adjustments of the instrument's pitch. Tuning is performed by changing the length of the bore on both the clarinet and the flute, by adjusting the barrel and the head joint respectively, but the structure of the bassoon is complex and doesn't really include a part that can be extended.
For this reason, tuning is performed by changing the length of the bocal that is inserted into the instrument. For example, a long bocal can be used during hot periods, which cause the instrument's pitch to become naturally higher, and a short bocal can be used when low temperatures lower the instrument's pitch.
This bocal is rarely used, due to small demand and high prices. The sound is absolutely wonderful, but they are extremely expensive. Zinc plating It is possible to buy an unplated bocal instead of one that is silver-, nickel- or gold-plated.
Lengths All Heckel bocals can be supplied in different lengths from 0 to 4. The standard is that a no. Shapes In addition to the standard shape, a Heckel bocal can be supplied with a flatter bend for taller people. Special shapes can be manufactured, according to what the bassoonist actually wants. They can, of course, be supplied in all materials and lengths. Both of them satisfy the production process parameters but they are quite different from each other.
Their resonance features can be described thus:. Less muffled and is comparable with a thick-walled bocal. It is possible to play louder, which has its advantages in a large orchestral setting. A larger, direct sound, resulting in more stability.
This can be played with less effort, but can be really powerful in solo passages. These bocals are silver-plated, but can also be supplied with gold plating.
The tone can appear from virtually nowhere, with great and immediate resonance. Tremendous for use in staccato passages, as well as legato pieces; its rich graduation of tone is remarkable.
Paraschos The wooden Paraschos bocal is made from two halves of milled rosewood. These are glued together ingeniously so that the glue joint is really strong. There are metal tubes at either end. The tip, where the reed is attached, has a brass insert and the cork is glued to a brass tube.
The bend, where the wood is weaker, is reinforced on its inner surface with a brass strip. Warning: wood is always weaker than metal! The Popkin and Glickman Book, a fantastic resource for every bassoonist, has details to help illustrate the end of the bocal slightly bent upwards. See pgs. Happy Bassoon-ing, Everybody!
