To kick off our series on the pentatonic scale, we look at what it is, and the fact that there are two different types... Major & minor! These are totally different scales and must be treated differently, even though they are both pentatonic scales.
A pentatonic scale is a 5 note scale, rather than our more usual 7 note major or minor scales. The pentatonic is very much based on the 7 note major / minor scale, but only uses 5 of the 7 notes to construct it. It therefore shouldn't be too surprising that the pentatonic has a major and minor, just like the full 7 note major and minor scales.
The really cool thing about the 5 note scale vs the 7 note, is that you have no semi-tone notes. All the notes in a pentatonic scale are either a tone or tone and a half apart, and therefore it is quite tricky to find any clashing notes when playing over a basic chord structure. This is one of the reasons why guitarists often gravitate towards this scale when soloing, as every note should sound great all the time!
