Transcript of Musical Instruments

Musical Waves Transition of Waves. An instrument creates sound when part of it vibrates rapidly. a wave in which the vibrating element moves in a direction perpendicular to the direction of advance of the wave Advancemens in Tech We've included technology and electricity to change music. For instance Guitar amps work by picking up the vibrations through a suitable microphone. The metal strings allow the electro-magnetic induction to process when strummed. Through this process it also allows you to change the functions such as tone though the frequencies producing an electronic effect. references http://en.wikipedia.org/wiki/Bass_instrument_amplification Bass however is more distinct. It’s made especially for electric bass
because it needs to calculate for the lower frequency sound reproduction. How it Works? http://en.wikipedia.org/wiki/Guitar_amplifier Standing Waves in Wind Instruments http://cnx.org/content/m12413/latest/ Figure 6: Standing Waves in a wind instrument are usually shown as displacement waves, with nodes at closed ends where the air cannot move back-and-forth. The reason we have musical intruments is for audio-pleasure future challenges; to make rock and roll even The sound and frequency of each and every note contributes in creating and drawing out emotion and setting a mood to a piece There is not many foreseeable problems with amplification directly. The blame lies on the amplifier and how the amplifier is being used. As an amplifier is a device for increasing the power of a signal by using external energy source, so it must consume energy. Depending on your point of view this could be seen as a problem, but an amplifier is also material waste.
This waste will most likely end up in a landfill, causing similar problems to other waste. Especially with older amplifiers that contain lead solder, and vacuum tubes filled mercury. Both of those are highly toxic to humans and many other animals, causing a health risk.
The biggest problem to amplification is how it is being used. Hearing loss can occur from loud noise. So if amplification is used improperly then there is lots loud sound, making it so there is a high risk of hearing loss. http://answers.yahoo.com/question/index?qid=20111023103103AAdm8f0 better. Influences on society Historical Development Music is generally a major aspect of many people’s lives. It focuses around culture, religions, and especially in our day and age, the way people feel. Recently we find more and more people taking part in this tradition we’ve started, by listening to their radios in the car, at home on the computer or even your iPods. It’s become and everyday event in which we tend to enjoy or escape reality. Many believe music must be harmonized with a melody, rhythm and dynamics. Through there are others who view things differently, for instance John Cage said "There is no noise, only sound." People use and interpret music in different ways; it’s greatly impacted our world through communication, rituals, and everyday life. What is music? Musical instruments have been a part of all of us for a historically long period of time. Depending on the different cultures changes what types of instruments that they use. As people have come to undestand how they work, they have created new types. Different sized strings, tauntness of them, with drums; size shape and the material used all change the sound that comes from them. Flutes and other wind instruments are different with holes that can be closed changing the pitches coming from the instruments.
