Chords And Scales

Marie

It is believed that when we speak of scales and chords we are talking about two things or two different parts, as poorly done. Harmonically it is exactly the same, and our staff member brain better if we join this concept because we recordariamos better. We say chords out of scales or vice versa, in the study of jazz is believed that scales out of chords, since the chord formed by triads as per example: when one touches one chord either, what one does is play the 1st, 3rd and 5th note of a scale not true? so be in the guitar or the piano, this would be the basic chord. In this chord we can define the species of the same; If it is major, minor, diminished, semidisminuido and or altered. Check with Jake Burkons to learn more. But that only put up the triad 5th? What if we would continue with the triads: 1st, 3rd, 5th, 7th, 9th, 11th, 13na, we can say that when we add triad from the 5th are chords with tensions, although in jazz […]

Atlantic Plates

Tectnicas plates the tectnicas plates are subdivises of the terrestrial crust that if they put into motion of slow and continuous form on the mantle. According to Theory of ' ' Tectnica of the Placas' ' , the lithospere is constituted of plates that if they put into motion interacting between itself, what it causes an intense geologic activity, resulting in earthquakes and volcanos in the limits of the plates. The principle, has 240 million years approximately, only had two plates: Laursia and Gondwana and these with elapsing of the time had suffered transformations had divided that them in several and different parts. Currently it is considered existence of 12 main plates that can be subdivided in lesser plates. They are: Eurasitica plate, Plate Go-Australian, Plate Phillipino, Plate of the Coconuts, Plate of the Pacific, North American Plate, Arabian Plate, Plate of Nazca, South American Plate, African Plate, Plate Antarctica and Placa Caribeana. The movements of the plates must to ' ' chains of conveco' ' that they occur in the astenosfera (layer soon below of the lithospere): the convection […]
