blues music scale
Where does the blues scale come from?
I mean like its foundation, what made it become the blues scale, when was it first used in music?
It’s basically a pentatonic scale with “crush” or blues notes added. If I’m not mistaken this scale is present in several cultures. Native Americans for example used.
A pentatonic or five note scale can be associated with a 7 note modal scale with tones that cause dissonance removed. The tones carrying any possible dissonance are the 2nd & 6th. This has to do with overtones. (Ask a physicist or an acoustics specialist more on that one.)
Play the black keys on the piano and Voila ! You have a pentantonic scale in E flat. You can play any black key simulatenously and it sounds great. if you added a 2 and a 6, you’d have an E flat aolian (modal) scale. The 2 would be F natural and the 6 would be C flat (usually called B natural.) And you’d have to have some music training to make it sound good. You couldn’t just hit any note and not bother anyone.
The minor blues use the following intervals: 1, flat 3, 4, 5, flat 7, with a blue note of flat 5 (tritone). If you omitted the tri-tone, and were strictly pentatonic, you would have created something very melafluous because third, fourths, fifths and sevenths are “nice” intervals and I do not think this is a particularly culturally biased statement, though I wouldn’t be surprised if several cultures disagreed with that assessment.
