As we have observed already, every one of the four parts must flow melodically and freely.
"Johann Sebastian Bach"
Johann Nikolaus Forkel and Charles Sanford Terry
All are phenomena of harmonic notes striving melodically onwards, either upwards or downwards.
"Wagner's Tristan und Isolde"
George Ainslie Hight
Continuity was assured; lovely or unlovely harmonic dissonances were always arising, and being resolved through the collisions and onward movement of parts; the music, both melodically and harmonically, could be as expressive as the particular composer's powers allowed.
"Haydn"
John F. Runciman
