It was Pythagoras of Samos, who lived about five centuries before Christ, who studied sound with an instrument called monotone (one string), he identified the seven basic sounds with which music is constructed.
It took about 15 centuries since Pythagoras, until the Middle Ages, the Benedictine monk Guido d'Arezzo, introduced the Pentagram (five lines on which musical notes are written), and gave names to each note, taking the first syllable of each line of a poem or hymn to San Juan.
From then until today, they have written countless musical works that vibrate sounds that touch us in the depths of our feelings.
