Significance of guitar as a music instrument Essay

Significance of guitar as a music instrument - Essay Example For example, guitarists frequently pull or push strings by their fingertips of their left hand to create notes or to make the note slip downward or upward. By adjusting tuning pegs, guitarists can change the tension of the string in order to produce varied sounds. Guitar provides a rhythmic pulse when combined with singers and other instruments. It is argued that singers are able to maintain the rhythm of a song when accompanied with guitar (National Guitar Workshop, 2003). It helps singers stay on the course and prevent them from going off key as they move from one verse to another. This is arguably true because guitar can produce standard key notes as long as the guitarist is able to maintain the rhythm. In fact, most singers use guitar to trace a forgotten or lost key note in their songs. However, in most cases, guitar is used to support lead instruments and singers’ notes. Some bands use two lead guitars to create interweaving melodies (Miller, 2009). Nevertheless, other bands use one lead guitar to perform instrumental melodies as the second lead guitar provides improvised flourishes. Guitar also provides harmony, especially when a group of notes are played together or in a group. It easily harmonizes other musical instruments in a band (Forman, 1999). In a band with both lead guitar and rhythm guitar, the lead guitarist can produce amazing rhythms when accompanied by rhythm guitar. When solos want to take a break from singing or when translating from one verse to another, guitar helps maintain the rhythm and makes the song more dynamic. It is also argued that guitar also plays the role of a piano if the piano is absent (Miller, 2009). However, it is generally accepted that guitar acts as an instrument that fill out cords and notes that other musical instruments cannot play. In fact, the chords of louder instruments like brasses are covered by guitar. It also

The Catastrophes Experienced in the Modern World Essay

The Catastrophes Experienced in the Modern World - Essay Example Some human actions have played a role in creating global warming and escalating the calamity in the world. The primary cause of global warming is the greenhouse effect. Upon reaching the surface of the earth, an amount of sunlight is absorbed, while the rest radiates back to the atmosphere (Balachandran 107). The sun that radiates to the atmosphere does so at a longer wavelength, with some wavelengths being absorbed by greenhouse gases in the atmosphere. Some of the heat energy that would be lost to space is reflected the earth’s surface by the greenhouse gases. Thus, the decisions of human beings to adopt the widespread use of greenhouses have significantly contributed to the escalation of global warming. The increase in global warming can be attributed to high incidences involving the use of greenhouse gases (Atwood 15). The emission of carbon dioxide also causes global warming; burning of fuels plays a role in escalating the incidences of global warming all over the world. Fuels such as diesel, natural gas, petrol, oil, organic diesel, and organic petrol mainly contributed to global warming and overall environmental degradation. Industries emit harmful carbon dioxide gas to the environment, causing massive destruction of the environment. When carbon dioxide is released to the environment, it remains in the atmosphere for as long as 100 to 200 years. The increased concentration of carbon dioxide in the environment creates a rise in earth’s temperature. Another factor responsible for the rise in global warming is the increased pollution caused by the clearing of vegetation cover. Human beings invade forests and clear vegetation and trees in order to settle.
