Tuba is a musical instrument. It was developed first in the early years of the 1800s. Its huge size and deep sound are considered as its specialty. The instrument is made up of three valves, vertical tubing, flared Bell, cone-shaped bore, and a cup-shaped mouth.
Different traditional techniques are used to create Tuba and provide shapes to their segments. Machinable brass is used for the development of Tuba. Different segments are molded and then attached to complete the creation of Tuba. The instrument was developed to produce brass sound using brass components.
Musical Sound of Tuba
Tuba belongs to the type of brass wind instruments. These instruments produce sound due to the buzzing of the user’s lips on the mouthpiece of Tuba. Due to this, the column of air present inside the musical instrument starts vibrating. Then, it exits through the way of the bell, and a musical sound is created.
The modern design of Tuba has changed as compared to its early years of creation. It is a huge and heavy instrument. It contains a huge bell of 14-30 in diameter. Its tube is shaped like a coil in which the bell shows on the top. However, several segments and variations are there in the instrument.
The bell is an important part of the instrument, so it has to be positioned strategically. The bell impacts the whole quality of the tone that Tuba produces. Some brands of Tubas have a bell on the right or left side. So, it depends on the strategy, different brands of Tubas position accordingly.
Most of the varieties of Tubas are developed with four valves that belong to the Piston type. But some instruments are developed with two to six valves. Some varieties of Tuba also contain Rotary Valves. The Rotary Valves work faster than the Piston valves but are not much durable.
A huge cup-shaped mouthpiece is inserted in the Tuba. You can purchase Tubas in 5 keys that are completely different. They are:
- Double B flat
- Double C
- E flat and F
- Double G Contrabass bugle
The main item used to make traditional Tubas is Brass. This is why they are also called Brass Instruments. Brass is an alloy. It contains two elements- copper and zinc. Some other metals are also used, such as tin and nickel. The addition of these metals provides extra features to the musical instrument.
Yellow Brass is the type used often in the making. It contains a 7:3 ratio of copper as well as zinc. This type of brass is yellow and can be stretched or molded into different shapes. Some other types of brass are also used in making when different characteristics are required. Silver Brass is also good for making this as it contains copper, zinc, and nickel.
Besides brass, only one or two other materials are used in the making. The screws are mainly created using stainless steel. In a few varieties, valves and the vertical tubes are coated with two alloys- chromium as well as nickel.
