I am having difficulty trying to get any kind of benefit from practicing major and minor pentatonic scales to use for improvisation. The problem is that the 1,2,3,5,6 shape in the hand is not particularly useful to produce a melodic line. I must, therefore try to remember which notes are in the scale which due to its asymmetric form always creates problems especially when descending. For instance if I start on the 3rd of the scale, the form is then 1,3,4,6,7. Or on the 2nd it would be 1,2,4,5,7.
Am I thinking about this in the wrong way or is this a difficulty most people have when using pentatonics?
