Famous quotes containing the words harmonic and/or motion:
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
“Thence, flow! conceit and motion to rehearse
Pastoral terrors of youth still in the man,
Torsions of sleep, in emblematic verse
Rattling like dice unless the verse shall scan
All chance away....”
—Allen Tate (1899–1979)
