In this book  I describe one small corner of twelve-tone\/ musical set-theory in which groups of three pitches (trichords) are used as building blocks for twelve-tone rows. Each row only uses one set of three pitches (trichord) to generate the entire content of a twelve-tone row. The twelve-tone rows generated from these 12 trichords each have a specific sonic quality and have structural relationships to each other as well as to the symmetric scales commonly used in jazz. These relationships provide us with a system of \"harmony\" which can be used when improvising.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e-John O'Gallagher\u003c\/span\u003e\u003c\/p\u003e","brand":"Twigg Musique","offers":[{"title":"Default Title","offer_id":44878975533109,"sku":"ADV14278","price":56.95,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/7187\/7173\/files\/2097759-gf.jpg?v=1767007736","url":"https:\/\/www.twiggmusique.com\/fr\/products\/twelve-tone-improvisation-a-method-for-using-tone-rows-in-jazz","provider":"Twigg Musique","version":"1.0","type":"link"}
