Ever played mahogany blues guitar? No, it won’t produce depressing music! In fact, the blues guitar scales feature pentatonic scales with one additional note, which is called “blue note”. This is because it renders an apparent “bluesyness” to the pentatonic scale.
There is only one difference between guitar scales and scales on any other musical instrument – you can play guitar scales in more than one way thanks to the strings of guitar. You can play a unique note in 3-5 ways with this instrument.
Using Blues Scale In Lead Guitar Playing:
You can produce a minor pentatonic scale by using 1st tone (root), flatter 3rd, 4th, 5th, and 7th tones of a major scale. You don’t have to use 2nd or 6th tone. You can produce a minor blues scale by adding a flatted 5th tone to the scale. In the A key, this produces a scale with the following notes in it: A, C, D, Eb, E, and G.
There are people who don’t distinguish between minor and major blues scales. Remember, a blues scale means the minor version.
You can produce a major pentatonic scale by using 1st, 2nd, 3rd, 5th, and 6th tones on a major scale. In the C key, it would produce C, D, E, G, and A notes. To create a major blues scale, add a flatted 3rd tone that gives you the following notes in C key: C, D, Eb, E, G, and A.
The rules regulating relative major as well as minor scales are working here. Observe the keys of A of minor scale and C of major scale. You will notice similar group of notes. Both the scales are relative, which means they comprise of the same notes.
The minor blues scale of A key has A, C, D, Eb, E, and C notes and the major blues scale of C key contains C, D, Eb, E, G, and A notes. The notes are same. Where’s the difference then? It’s in the starting point!
This is a common occurrence in music. And if you are playing a mahogany blues guitar, you will find that its scales are doing double duty! Once you master one pattern, it becomes useful for one major, one minor, and 2 keys.
Playing The 12 Bar Blues Progression:
This is simple. Suppose, the first chord of the progression is A7, make use of that minor blues scale over the song to solo. You need not alter scales at all.
Although the above way is not the ultimate one, it’s still preferable due to its simplicity, especially when you are learning to play mahogany blues guitar. There are other ways, too, to play 12 bar progression or other type of chord progression, for that matter. The common approach is to use a combination of minor and major blues scale.
So, are you ready to learn playing a mahogany blues guitar? Once you master the skill, you will be able to create sounds or musical notes that you wish to hear and play.
