Друзья! И снова нужна ваша помощь. Помогите перевести, пожалуйста:

Ni Dan Meri (Two-step meri). Take for example Tsu-meri. When you meri this sound again, you get a sound similar to Ro. Similarly, if Ro is meri-ed as far as possible, you will be able to produce the same pitch as the Ro of a flute two sun (approximately 6 cm) longer or even lower than that.
