Richard Llewellyn said this quote
“ Sing, then. Sing, indeed, with shoulders back, and head up so that song might go to the roof and beyond to the sky. Mass on mass of tone, with a hard edge, and rich with quality, every single note a carpet of colour woven from basso profundo, and basso, and baritone, and alto, and tenor, and soprano, and also mezzo, and contralto, singing and singing, until life and all things living are become a song.O, Voice of Man, organ of most lovely might. ”
