EXPRESSION

"There is something common between the philosophy of Orff and Greek traditional expression: it is the primary unity of music, movement, and language, a triad that forms the central idea of Orff-Schulwerk."
Nefeli Atesoglou, Rythms 36-37, The Hellenic Face of Carl Orff, 2003, p. 35
"Singing, dancing, playing instruments are equal, complementary, and connected forms of expression".
Wolfgang Hartmann, Looking at the roots, 2021, σ. 29
