It's Time to Move Beyond Equal Temperament

Over the years, we have braintered by listening to many classical music and rock music that has been played on electric pianos. The music played on these instruments can not appreciate the real art by dullening our ears too much. Tuning of the piano no longer requires its equal temperament system. Modern technology has evolved as long as it is possible to change the key of any one piece simply by pressing a button on an electric piano. In today's average temperament, the representation of various works of artists is basically restricted to world standards.

One of several systems of such adjustment, such as the system that is practically impossible with keyboard instruments, the average tone temperament, the system close to natural tuning, and the keyboard instrument is commonly used Equal temper. A system given an octave-based scale divided into twelve completely equal semitones, or just tone

There are two main series in the tuning system: equal temperament and synchronization. By dividing the octave at equal intervals on a logarithmic scale, an average scale is established. This gives a completely evenly divided scale, but the frequency ratio is irrational. The scale is established simply by multiplying the frequency by a rational number, which results in a simple ratio between frequencies, but the division of the scale is not uniform. One of the main differences between equal temper tuning and tuning is the difference between acoustic beats when two notes are pronounced together. Both systems, as with most music, generally have a scale that repeats at each octave interval. It is defined as a frequency ratio of 2: 1. That is, each time the frequency is doubled, the specified ratio is repeated.

All semitones are the same as temperament levels. Each represents the same frequency ratio 05877. The big advantage of the average scale is that music plays well with all keys. In other words, for instruments tuned to the equal temperament, any of the 12 semitones can be used as "Sa". You do not need to change the adjustment each time you change the rag. Since the keyboard instrument is tuned beforehand, it follows the equal temperament. According to Boulanger (2000), the word sound is related to a very clear and special emotion caused by the stimulation of the ear mechanism. The external cause of emotion is also related to sound. Everyone who vibrates is an external cause of emotion. Vienna and violin in the vibrating state are the cause of external emotions. The body in a vibrating state becomes a sound source. Vibration is a periodic reciprocating motion around a fixed point.
