# Are Modern Musicians Lazy: A Comparison between the Lengths of Modern and Classical Music

Extracts from this document...

Introduction

Are Modern Musicians Lazy: A Comparison between the Lengths of Modern and Classical Music Hypothesis In this project I will endeavour to find out if "Classical" Music really is longer than "Modern" music. I have always enjoyed listening to music and have quite a broad taste in music. There has been a disturbing trend recently in music for songs to be quite short. Some bands appear to write songs which last no more than 2 minutes, which is hardly even value for money (considering you pay about �14 for a CD that sometimes lasts for a mere 25 minutes). Therefore, for this project I have decided to see whether Classical Music really is longer than Modern Music, and hence, is probably better value for money. However, when phrased as it is above, the project will be far too broad for me to investigate properly, so I will have to set limits to define exactly what I am investigating. By modern music I mean all music from the past 18 years, so any music released since the year I was born up until today. This will include as wide a range of different styles as I can get my hands on, so everything from "Duran Duran" to "System of a Down" will be included. ...read more.

This will result the in the calculator displaying a number between 0 and 2000 (if the parent population is 2000). I have used that number as the track number to sample. The program then loops back and displays a different track number to choose and this repeats ad infinitum. The number it generates, however, is to a few decimal places, so I rounded the number to the nearest integer when choosing my samples. Here is a sample of results from the calculator program (where 2000 was specified as the parent population): 15.375 679.8 103.667 1729.911 1825.441 9.873 394.602 1592.719 711.828 110.158 2.861 50.193 234.123 592.098 399.912 Why this method produces perfectly randomly numbers between 1 and 2000 When the Ran# function of a calculator is inputted, the calculator returns a randomly generated decimal number between 1 and 0 (0<x<1) which is 9 digits long. When this number is multiplied by 2000, it can be seen that a number between 0 and 2000 will be generated. If, for example, a random number of 0.00598375 is generated, then 11.9675 is returned by the calculator. This I will round up to 12, and hence I will choose the 12th track from my list. Sample Size For this project to be a success, my samples have to be randomly chosen, but they also have to be of a suitable size for my sample population. ...read more.
