The minor pentatonic scale, the most popular scale used for lead guitar in rock and blues music is dark and bluesy.
There are many different ways to look at the minor pentatonic scale like all the other scales. Okay, just start to look at how it is called. Minor Pentatonic Scale => Minor and penta and tonic. Let's analyze these 3 words. What do you think?
Minor: The scale should sound minor and also we know from the An Introduction to Guitar Pentatonic Scales article that it is derived from the natural minor scale. Penta means five and tonic represents the notes in the scale. Then we can say that the minor pentatonic scale is a part of the minor scale and has just five notes.
Here comes the question: Which part of the minor scale and why?
The five notes of the minor pentatonic scale are the first, third, fourth, fifth, and seventh notes of the natural minor scale. Or we can just say we left out the second and sixth notes of the natural minor scale. By skipping these two notes the scale has a more primal character and still keeps the properties which makes a scale minor. The scale has no half steps so that the scale is more suitable for an aggressive sound. And it is easier to play and remember five notes than seven notes on the fretboard.
