pentatonic scales
Penta means 5 so basically penta-tonic would mean 5-tonic or 5 note scale.
Actually there are many pentatonic scales that people use. Not flaming anyone, rylche dont get me wrong, but the G minor is not THE pentatonic scale.
To get a short cycle of pentatonic scales take a C major scale C D E F G A B C and take out your 4 and 7 notes, you will get C D E G A C, thats your major pentatonic, the relative minor to this would be starting at the 5 note of this or the 6 note of the original scale, the A. A C D E G A.
To play this start with your middle finger on your A string 3 fret, or your C note and just move down your strings;
A STRING 3 fret 5 fret, Played with middle and last finger
D STRING 2 fret 5 fret, played with pointy and last finger
G STRING 2 fret 5 fret, Played with pointy and last finger
The A minor works on the same principle as this remember 1 finger per fret, isolate the 4 frets that you will be using at first to train you muscle memory.
Starting on the D E G notes will provide you with another 3 pentatonic scales.
D E G A C D
E G A C D E
G A C D E G
these 5 scales are the pentatonic scale modes and all of them can be used over most modal songs, or songs that dont change key in simple terms in C. The fingerings for all of the scales are different but they are all basically the same scales. remember use tastefully to prevent sounding like chinese music everytime you use it. For listening go and buy a few stanly clarke albums and have a listen, victor wooten as well.
sorry for the long post. cheers
