{"product_id":"john-s-rules-music-book-john-o-sullivan-9781838121921","title":"John's Rules Music","description":"\u003cp\u003eThis book describes some rules that I came up with and follow when I am composing music. These rules could apply to any tuning system such as my own Eagle 53 tuning and other alternative tunings. There is also a list of what I consider to be good harmony and melody intervals over a six octave range. The book is aimed primarily at people who use alternative tunings (i.e. tunimgs that are different to the standard Western musical tuning: 12 Tone Equal Temperament). There are only 20 pages of text in this book, the other 80 pages list 96 scales and 2196 'legal' intervals.\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49583847375121,"sku":"GOR013480606","price":3.9,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1838121927.jpg?v=1751217613","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/john-s-rules-music-book-john-o-sullivan-9781838121921","provider":"World of Books ","version":"1.0","type":"link"}
