Silence-and then with a shout the Tunable bells broke forth, rocking the tower.
"The Ship of Stars"
Arthur Thomas Quiller-Couch
For wanting the currantnesse of the Greeke and Latine feete, in stead thereof we make in th'ends of our verses a certaine Tunable sound: which anon after with another verse reasonably distant we accord together in the last fall or cadence: the eare taking pleasure to heare the like tune reported, and to feele hie returne.
"The Arte of English Poesie"
George Puttenham
As your single words may be many waies transfigured to make the meetre or verse more Tunable and melodious, so also may your whole and entire clauses be in such sort contriued by the order of their construction as the eare may receiue certaine recreation, although the mind for any noueltie of sence be little or nothing affected.
