Watch the Minor Pentatonic Scale online guitar lesson by Jeff McErlain from Blues Guitar Survival Guide - Lead
The A minor pentatonic scale is most likely the first scale you learned on the guitar and there is a lot of music in those notes. A pentatonic scale is a 5 note scale as opposed to the normal 7 note scale. It is simply a natural minor scale with the 2nd and 6th degrees removed. An easy way to look at it is as a minor scale with the half steps removed. For example A minor is A B C D E F G, A minor pentatonic is A C D E G. By removing the B and F we remove the notes that can be problematic at times, especially the F. Please check out the 4 note groupings and one string at a time methods, these really helped me solidify the scale and the notes on the neck.
