Why is the musical scale the way it is: 12 keys: 7 major, 5 minor?

Thank you for asking ! The reason why the musical scale is composed of 1 2 keys , with 7 major and 5 minor keys , is a complex and fasc in ating topic that has evol ved over time . There are several theories and hypoth eses , but no single explanation can fully account for the orig ins of this particular scale . \n One theory is that the 1 2 - key scale is based on the natural harm onic series , which is a series of notes that occur naturally when a string is v ibr ating . This series consists of the first 1 2 harm on ics of the string , and these notes are the ones that are used in the standard musical scale . \n An other theory is that the 1 2 - key scale is based on the way the human ear perce ives and processes sound . Research has shown that the human ear is most sensitive to frequencies within a certain range , and this range is roughly equivalent to the range of notes in the standard musical scale . \n It ' s also worth not ing that the 1 2 - key scale has been used in many different cult ures and musical trad itions throughout history , and it ' s possible that the similar ities between these scales are due to a shared cultural or historical influence , rather than a single , universal explanation . \n Over all , while there are many theories and hypoth eses about the orig ins of the musical scale , there is no single , definit ive answer . The 1 2 - key scale is a complex and mult if ac et ed topic that continues to be studied and deb ated by mus icians , music olog ists , and sch ol ars today . </s>
