Interpret the piano tuning 解讀鋼琴音律

From an artistic point of view, tuning is the pursuit of the beauty of harmonious proportions, which is equivalent to the harmony of colors that can be seen by the naked eye, and the preparation before the artist has started to write.

When the tuner was sitting in front of the piano, he began to concentrate on pressing the first key. The moment he touched the key, he clearly saw the hammer inside the piano rushing forward and hitting the strings. The frequency of the vibration was its pitch, while listening to the sound, the ears direct their hands, twist the tuning pins connected to the string, and change the tension of the string to return the pitch to its own pitch. Constantly beating, constantly making corrections, setting the appropriate pitch for each tone on the piano until the eighty-eight keys are completed, and all the notes are actually based on the twelve equal temperament tuning system, because this system can perfectly formulate a communion relationship between different sounds.

Temperament comes from the Latin word ‘Temperare’, which means "mediation and relaxation"; the French word ‘tempere’ means "appropriate mixing of various components" to create a suitable mixture of opposing things. [1] At present, the most commonly used tuning method is the twelve equal temperament, which divides an octave into twelve equal parts, and each equal part is called a semitone. The frequency of the higher octave is doubled (that is, the frequency is doubled). The frequency of the octave is divided into twelve equal parts, that is, it is divided into twelve geometric series, that is, the frequency of each tone is the 12th root of the previous tone. For example, A440Hz pitch, and A# will be 440 times the 12th root of 2, that is, A#466.16Hz, and so on.
