musical instruments - the Scientia Review
Bluegrass Music A form of folk music, Bluegrass music was inspired by the music of the Appalachian Mountains. It was very common during the 17th and 18th centuries. The instruments used in this music include the fiddle, five-string banjo, guitar, mandolin, and upright bass. They are often joined by the resonator guitar and the harmonica. Folk String Instruments Stringed instruments that can be broadly classified as folk instruments – such as the hammered dulcimer, the banjo, and the hurdy-gurdy, among others - are typically absent from traditional ensembles. There are hundreds of these diverse instruments, and they have originated in many locations at many different times around the world. The Sounds of Folk Music Folk instruments are usually played by plucking rather than bowing or strumming, and the resultant auditory effect has come to be characteristic of folk songs.
Electrical Instruments Electrical Instruments Electric guitars and electric basses by extension evolved in the twentieth century because of the need for amplification. Early instruments used a conical resonator to amplify the emitted sound waves directly on the guitar; more recent versions connect the guitar to an amplifier that acts as its own speaker. All electric instruments output an electrical sound signal that can be played through a speaker. This gives them the advantage of amplifying their sound to any desired level, which can be very useful during performances. The class of electric stringed instruments contains a large majority of electric guitars and basses. Classical instruments, such as the violin, are also currently available as electrical instruments. These instruments come equipped with all the features of a classic violin, but are also able to output to an amplifier.
