Using a smartphone metronome app, we sang "Lapis Lazuli Earth" a cappella. It started to sound beautiful. [Hokuryu Town Sunflower Chorus]

This was our third independent practice session. We were able to harmonize as a group of seven. In the second half, we practiced singing "Ruriiro no Chikyu" (Blue Earth) a cappella. 😅 [Hokuryu Town Sunflower Chorus]
