I've been playing guitar for about 1 year and a half now and so have decided to start looking at scales but am struggling.
If we take the Am pentatontic scale as that is what i'm looking at. The first scale shape starts on the 5th fret. The next shape on the 7th, the next on the 10th etc down to shape 5 which starts at the 15th fret and ends at the 17th fret?
Well my problem is if i wanted to play in the Dm pentatonic wouldn't that mean that shape 1 started at the 10th fret. Surely then shape 5 will end at the 22nd fret? My guitar only has 20 frets so this seems odd. Would this mean that is i wanted to play in the Ebm pentatontic scale (does that even exist? the minor penta scale starting at the 11th fret anyway) would end even lower down?
Also, if i am playing for example, in the Bm pentatonic scale which starts at the 7th fret, what is happening to all the unused freboard space above? is none of this in the same scale?
I'm pretty confused. Cheers
