Most guitarists will start out playing something related to the pentatonic... its just THAT common and important.
Primary Concepts for This Skill
The pentatonic is a 5-tone scale (‘pent’ or ‘penta’ for 5).
In Western music the most common pentatonic scale excludes 2 tones from the common major or minor scale to create a scale with only 5 tones. Typically, the scale degrees ‘4’ and ‘7’ are removed from the major scale to create a major pentatonic scale.
One of the important musical characteristics of the Western pentatonic scale is that it doesn’t contain any half steps – this makes it a bit easier to use for musical results. Think of the pentatonic scale as having training wheels – you can’t really go wrong 🙂
A minor pentatonic scale also contains 5 tones and the same notes are removed, but they have different scale degrees in the minor scale (compared to the major scale). For example in the key of C major, we’d remove the ‘4’ and ‘7’ – F and B. In C major’s relative minor scale: ‘A’, we’d still remove the F and B, but in A minor those are the ‘2’ and the ‘6’.
