When a note is played, pressing the key activates a string to cause sound vibrations. Each string is tuned to correspond to a note in the musical scale. Each note is a step in the scale, and using these notes a musician can blend the sounds to create harmony or discord. Similarly, names blend conscious forces to create mental harmony or mental discord. The individual keys, although important, are not the music.
Music is expressed when the keys activate the strings.
If the keys are not used, there is no music. A melody can be played on numerous instruments which express the same musical composition by different means. In the same way, intelligence is universal and can be expressed by many different languages. The thought that the sky is blue can be conveyed in as many languages as exist. Yet the thought remains abstract until expressed through language.
