Thank you for the subtitles! ;) This 3rd and 5th flexible means that she changes the pitch so that the interval becomes higher or lower at the end of the sound ? I also think players can help composers a lot. So I always ask them. One trombonist player helped me more than my teacher already haha. Very nice video and nice music written with a lot of rhythm and dramatic hits as percussionists love. Thank you for sharing your inspiring video and make us learn even from the distance. Best of luck with your concert. And I wish I was there. Hope I can visit Taiwan soon! Inés.
