Can someone please tell me why there are 5 different patterns to Penatonic scales?

I mean if you can move them, why do you need more than one? All are movable up and down the fretboard? Right? So why does each need 5 patterns and how do you know which one to use? This has really been bothering me as I try to lean each pattern for Major, Minor, Blues, country & etc. That's a lot to memorize. Thanks for your answer. Nick

Do you mean in a straight-forward sense - like, the patterns correspond to the same notes within that respective pentatonic scale (I, II, III, V, VI) such that the different patterns are just the way to play the same notes within that respective key along the entire length of the fret-board? Because, for ex., a pentatonic pattern on the 5th-fret is in Am, but if you played that same pattern on the 12th-fret you would be in Em. Or are you referring to complex music theory like why are there different modes of a scale?

I assume you know the 5 notes are in a major scale or natural minor scale; we just remove the notes creating a half step relationship. In a major scale those are the 4th and the 7th. I like to think the pentatonic originates back in medieval times when churches were popping up. You have monks singing Gregorian chants in these huge cathedrals. The pentatonic scale resonates within the chamber creating sympathetic vibrations throughout. As a result the church (at the time) banned notes from the scale labeling them the 'Devils tritone' or the devil's notes; these notes correspond to the 4th and the 7th of a major scale, of the 2nd and 6th in a minor scale. The dissonance was thought to conjure evil spirits within the soul. Now along comes the classical period with Bach, Beethoven, and others. Rules for writing music were created (Counterpoint and music harmony theory). The rules made it safe (in the eyes of the church) to play these notes as long as it fit properly within the tonal center of the music. So we change the keys by a series of shared notes common in the different keys and so add the other tonalities to the melody; it's a work-around to playing the devil's notes in Christian music. Now add that to the growth of the African spiritual and you have this amazing blend. But at the essence the pentatonic scale stands firm in western culture. Good or bad, it is this force that has blended into so many different cultures that has conditioned our listening pallet to accept these 5 fundamental notes as a strong undercurrent to our popular music. Culture mandates that listeners must adhere to a 12 tone scale and any deviation is a risk that even the seasoned listener will not tolerate.
