Banjos are one of the oldest instruments in the history. They are a five string instrument. It is made up of wood and metal. One of the metal parts that enhance the sound quality is the tone ring. Earlier instruments did not have this part. Another crucial aspect is to capture the sound for more time. A banjo resonator helps in retaining the sound for a longer duration.

Anything that resounds or resonates has to be called as a Resonator. It could be a musical instrument or a scientific apparatus or else an electrical device. It naturally oscillates at some frequencies called resonant frequencies. It has greater amplitude than others. They are of various types like coaxial, dialectic, ceramic and crystal.

A resonator is basically adopted to produce louder sounds. People who want to make a sound louder and clearer which lasts for a long time uses resonators. This is a kind of membrane. In the past man used animal skin to make the covering. Membranes made of animal outer cover are stronger and durable. Nowadays synthetic membranes are also used.

Music is divine. Every living being is sensitive to music. Babies right from their mothers womb react to sounds of low pitch and music from the stage of a few weeks. Later on after birth they tend to respond to these sounds or music.

Guitars were the recent inventions in musical instruments. They have six strings instead of five. They were only thousand years old. These are products that does not use resonator. It is completely made of hollow wooden bark that used to provide high quality sound. The best part is it reduced the usage of animal skin.

The band performs live on the stage which is known as the concert. Nowadays instead of live performance the recorded version of the band are also getting published. This is just like a movie where a band records their music at a different place and later enacts and tries to sync the lip movement in order to look real. This whole setup is called an album release.

The actors have to synchronize their lips according to the speech. This process is known as dubbing. This actually gave the advantage of releasing the movies in different languages. Because it is difficult for the actors to speak multiple languages at a short notice.

Artists require lot of talent to perform live because there is only one chance we have and no scope of errors. However, in the case of movies and prerecorded songs we have multiple opportunities to commit mistakes. Historically many of the stars have emerged from the streets to the movie industry. People who perform live have all the three talent of singing, dancing and acting at the same time.

The constant depletion of the species can disturb the whole food chain which can pose a serious threat to our own survival. Apart from animal skin the musical instruments also use wood as the main ingredient. For this many trees are cut down that are displacing the animals from their natural habitat.
