Mozart K331 Analysis Essay example - 1232 Words

Analysis of W. A. Mozart’s Piano Sonata in A Major, K. 331: First Movement Classical composer Wolfgang Amadeus Mozart was born to Leopold and Anna Maria Mozart in 1756 in Salzburg, Austria (then the Holy Roman Empire of the German Nation). Mozart showed promise in music from an early age, prompting his father to assume the role as his instructor. His father described his son as a gift from God, and Leopold nurtured Wolfgang’s talents as such. Mozart would eventually travel throughout Europe with his musical family; however, it was in Salzburg that he would compose three piano sonatas in 1783. These pieces were most likely composed for Mozart’s pupils in Vienna, who were a significant source of income for him at the time. This paper†¦show more content†¦Fig. 1: First Movement, mm. 1-18. The tender melody Mozart presents in these first 18 bars is simple, with a lot of stepwise motion and small leaps. Adhering to classical style, he uses chords built on diatonic pitches and resolves dissonances quickly. Pairing a simple homophonic melody with simple accompaniment makes it easier to manipulate the theme in the coming variations. In Fig. 1, you’ll notice that the middle voice barely moves at all. In fact, it isn’t until measure 9 that we start seeing strong beats without an E in them. Also, the long-short (quarter-eighth/dotted eighth-sixteenth) motive remains constant until it too develops at measure 9. All of these techniques for a simple theme help Mozart develop his idea later. In the first variation, Mozart agitates the theme with the use of chromatic approaches and chromatic passing tones. Between the left and right hands, we hear an unrelenting series of sixteenth notes. Mozart also incorporates more use of dynamics than he did in the theme, by composing contrasting piano and forte sections. This drastic dynamic change happens in the A section of the variation. In variation II, another insistent figure is introduced: this time, triplet sixteenth notes. The melody in the right hand starts out very ornamented. Mozart then puts each melody note at the start of a flowing downward triplet arpeggio. The left hand emphasizes the strong beat throughout these triplets, and then the melody returns in the original

A comparison of the pros and cons of Hybrid cars to those of fuel-cells Free Essays

A hybrid car is a fuel efficient car which has 2 motors. One is electric motor while the other one is a gasoline powered motor. It has in addition to these a special system to capture braking energy store in an on board battery. We will write a custom essay sample on A comparison of the pros and cons of Hybrid cars to those of fuel-cells or any similar topic only for you Order Now A fuel-cell car produces electricity directly, the reaction of hydrogen and oxygen; the byproduct being water. A fuel –cell vehicle utilizes the electricity produced by the fuel cell to power motors at the vehicle’s wheel. A hybrid car has many advantages; they don’t use energy while idle, they also use less than gas motors at low speeds. With gas motors doing better at high speeds, it can deliver more power for a given motor weight. The electric motor works great at a time like rush hour and this way it doesn’t produce any exhaust therefore reducing smog levels. When a hybrid reaches a speed of 40 mph, the gas motor kicks in and gives a good feeling to the driver something most car owners are looking foe when on the highways. Hybrid cars also change the battery while running. Its disadvantages will include cost and complexity. It is a new technology and the cost is high. It also has its complications since the systems have to work together. If one system breaks then it might affect the others thereby making it really expensive to fix. Advantages of a fuel-cell car include:- low cost both in maintenance and purchase, its performance and rangeas read on ‘http://www.ucsusa.org/clean_vehicles/cars_pickups_suvs/fuelcell-vehicles.html’, it is known to be a smooth, quiet and fun to drive. They are also widely available in most parts of the world. They have disadvantages as; they contribute to global warming, they pollute air since they ran on pure hydrogen.   Ã‚   My opinion is that let there be wide variety since we are all different and have different tastes so let the variety to chose from be available.
