ABSTRACT:
A beat finder is provided for accurately and repeatably setting a speed control on a turntable, for use by a disk jockey in quickly matching the beat of successive music selections using two turntables and a technique for matching the start of each beat, in a "no-pressure" environment, in as much time as required to accurately match the speed of the switchover. The position of the speed control at a the proper transition speed for a current musical selection as well as for a following musical selection is displayed for each of the corresponding turntables. These numbers are recorded on a "program form" to be used as a reference during the actual "real-time" club or disco performance. During the performance, the disk jockey need only cue up the next selection, set the speed control to the setting indicated on the program form and quickly match the start of the beat of the incoming musical selection with the current musical selection, by slipping or advancing a phonograph disk manually, knowing with confidence that the beat rate of both musical selections will match.
