{"product_id":"afw-00153116","title":"The Ancient Call: Calligraphy No. 13 for Trumpet and Orchestra","description":"This work creates a dialogue between the Western Equal Temperament system, performed by the orchestra, against the Persian Dastgâh\/Maghâm system, performed by a microtonal trumpet capable of playing up to 24 notes per octave.  As the music juxtaposes these traditions, it explores the tensions as well as commonalities that exist between the two.","brand":"Lauren Keiser Music Publishing","offers":[{"title":"Default Title","offer_id":50536383578191,"sku":"AFW-00153116","price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/1271\/8671\/files\/AFW-00153116.jpg?v=1790596912","url":"https:\/\/amadeussheetmusic.com\/products\/afw-00153116","provider":"Amadeus Sheet Music","version":"1.0","type":"link"}
