In my Japanese album, I had difficulty pronouncing the “つ”(Tsu) character. After studying it carefully, my conclusion was that you can pronounce it well if you force the sound out like you’re spitting. (Laughs) What I remember from the recording session was singing the 3-level high note seven times. (Did you ask the PD why?) He said he just felt like listening to it. He has it bad, doesn’t he?
