Application of Genetic Algorithm in the Process of Sound Evolution

The perfect solution came around the late 1970s in a format known as MIDI (Musical Instrument Digital Interface). In a simple explanation, a MIDI file is a blueprint, which is sent to a reading machine. This machine has various spectrum data programmed corresponding to different instruments. The rather small MIDI file is then read, and interpreted to match the desired synthesized sound. The quality of the sound produced depends on the

Music is remarkable for its special nature, which it is heritability. Music itselfs does not only give all music notes but innovation and inspiration from

Music has evolved too many different forms that we recognize today. We trace this development throughout time. Beginning in the middle ages, we have seen advancement from the Gregorian chant all the way to the Jazz of the 20th century. The current events, politics, religion, technology and composers can shape musical eras during time. Here I will look at the middle ages, renaissance, baroque, classical, romantic and twentieth century periods. I hope that a better understanding can be reached to why, when, where and who are the reasons for musical evolution.

In my implementation of fuzzy genetic algorithm ii followed the steps of genetic algorithm so I started with reading the data of KDDCup99 and creating a population, this population was composed of number of individuals which are the records in the KDDCup99 which means that each individual has an array of genes to hold the features of audit records. This was accomplished by first encoding audit record data into binary because some feature such as protocol type has value "TCP". Once i finished creating my initial population I evaluated every individual in the population to calculate its fitness using function below

In every culture known to human there are different forms of musical expression. Although nonhuman primates can’t produce music, they have very similar auditory structures, perception and behavioral responses. Humans say that music has an effect on social arousal and mood, similarly chimpanzees show an increase in social behavior and a decrease in agonism when music is played to them. Evidence shows that human and nonhuman primates have an ability to distinguish music properties such as the types of rhythmic or melodic organization. Although primates exhibit and ability to distinguish between rhythmic structures and show a preference for slower tempos, it is unknown if they have a preference for rhythmic patterns. Humans and Chimpanzees prefer consonant music over dissonant music.

Biological fitness is fundamental to the evolution of species. It is defined both by survival and reproductive success, determined by the contribution to the gene pool of the next generation. Accordingly, the individual that lives the longest and produces the most fertile offspring has the highest fitness. Fitness is hereditary, genetically based, and phenotypically expressed. Natural selection acts on the translation of phenotypic trait variation to maximize performance, to improve and protect the highest fitness state and allow it to go towards fixation. The modification in the genetic makeup of a population over time correlates with an increased average fitness. However, evolution is not linear. Every behavior, every feature

Throughout this chapter, we have learnt about multiple new concepts and topics such as the mutations, artificial selection,

Music is a significant element in most lives it takes a role in most cultures people believe in. Music contains a variety of elements within different genres such as the pitch, rhythm, dynamics, timbre and the texture. Different voices and different kinds of instruments produce a variety of frequent

Music has shaped the world we live in. It is a human force that is as natural as it is inevitable. The study of the history of music involves understanding the driving forces of musical evolution, including political and social conditions at the time that the songs were developed. Less discussed, however, is the affect of our world's soundscape on the development of music. Soundscapes (a concept developed by R. Murray Schafer) are inclusive of the noises in our environment that we have so internalized as normal that we forget to listen for them. However, the basic distinction between music and noise is, for the sake of this paper, rhythm and pitch. It is these two components that can be traced back to the geographical soundscapes of various locations. The very basic things that make music music arguably stem from locations of human life. Analyzing the

Evolution is a change in a population and is usually seen as a slow process, but the pace of evolution can be rapid. In this lab, two of the forces of evolution was tested natural selection and genetic drift. In natural selection, 60 beans were used, 15 of each of 4 different kinds of beans. For genetic drift 48 beans were used, 12 of each of 4 different kinds of beans. The exercises was repeated up to 10 generations. Maintaining the frequency of each variety of the beans from the end of one generation to the start of the next generation the population was rebuilt to 60 beans for the natural selection exercise and 48 beans for the genetic drift. By the end of the 10th generation, changes were seen in both forces of evolution. This shows that

Music has been evolving since its creation. This evolution of music has led to a vast variety of music that all people can enjoy. Artists who make good music, are praised and revered for their talents, and recently this has led to many aspiring musicians who want to acquire fame and fortune through their music. In the United States music in constantly evolving, and in recent years this evolution of music has sped up to a very fast rate. Music has evolved for many reasons including, improved technology, and change in culture, and a desire to create something new.

Natural selection is based on the concept “survival of the fittest” where the most favourable individual best suited in the environment survive and pass on their genes for the next generation. Those individual who are less suited to the environment will die.

This is a study of evolution using mathematical biology, show how sexual selection and natural selection play of each other and produce strange things in the animal world. Ornamentals shows

We hear music, sing music, play music, and dance to music. Music is another way for us to express our feelings beside the words. There are ten elements of music: rhythm, melody, harmony, timbre, texture, form, pitch, dynamic, articulation, and lyrics; these also the broad definition of the entire realm of the theory of music and how it is made. At the physical level there are four significant wave patterns, which are defined as frequency, amplitude, duration and timbre (Hast et al. 2009, pp.
