Rocking and rolling

Rocking and rolling (also rock and roll) is a name for cueing techniques used in sound recording and video recording, particularly in analog recordings.

In sound recording, the reels of an open reel tape machine were "rocked and rolled" by turning them back and forth by hand, to cue recordings for playback, and especially for editing, which was done by cutting and splicing the tape. With the passing of reel-to-reel tape recording into obsolescence, the technique is now scarcely used.
