It is close to being mathematically perfect, but not quite.\u003c\/p\u003e\u003cp\u003eAlthough the original western scales devised by the Greeks were simply multiples of certain lengths of vibrating string, many factors have conspired to make contemporary western scales a little more complicated. For example, to work out the frequency of any note on the piano you would have to apply the following formula:\u003c\/p\u003e\u003cp\u003ePn = Pa(12√2)(n-a)\u003c\/p\u003e\u003cp\u003eThis would tell you that the frequency of A is 440 Hertz, B is 493.88 Hertz, C is 523.25 Hertz, and so on. These are irregular increments and these irregular increments have implications for all the western scales - but, luckily for you, none for us here today. We're going to keep away from this stuff.\u003c\/p\u003e\u003cp\u003eTable of Contents\u003c\/p\u003e\u003cp\u003e- Basic basics\u003cbr\u003e- Notes and Scales\u003cbr\u003e- Keys\u003cbr\u003e- Chords\u003cbr\u003e- Jamming in C\u003cbr\u003e- Jamming Elsewhere\u003cbr\u003e- One More Key\u003cbr\u003e- Stop Reading\u003c\/p\u003e","brand":"East Coast Road Productions","offers":[{"title":"Default Title","offer_id":47075105931504,"sku":"2940045789653","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940045789653_p0.jpg?v=1763683097","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940045789653","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
