.

The length of the loop, of course, controlled the length of the repeated sound, combined with the desired content of the composer. On a standard reel-to-reel, one could loop, at most, a few seconds of music or sound. Some composers were satisfied with this approach, but there were other methods to allow for longer loops. For example, one could place two reel-to-reel machines side by side and string the tape between them, using one machine for playback and the other simply as a pulley for the length of tape. By using this or other methods, some composers could create very long loops which allowed for lengthier fragments of sound. When recording his landmark 1978 ambient

One of the more novel uses of tape loops were heavily utilized by French electronic pop composer Jean Jacques Perrey (sometimes working with American composer Gershon Kingsley) on a series of mid-60s albums on the Vanguard label. Their loops often had tight, multiple splices in them to create their frantic rhythmic loop effects, to which they added conventional instruments and synthesizers playing generally familiar instrumental up-tempo tunes. Their composition, "Baroque Hoedown", from their 1967 album, "Kaleidoscopic Vibrations" was adopted by Disney for their "Starlight Parade" event at Disneyland and Disneyworld, and was used by filmmaker Mike Jittlov

 -- which can generally provide similar results with less effort—overtook much tape loop use, beginning in the mid 1980s. To create a loop digitally requires nothing more than highlighting a section of already-recorded music or sound and clicking on a 'repeat' or 'duplicate' icon as many times as you want the loop to repeat. Some musicians and composers, however, continue to use analog tape loops for various reasons.

Loop Pedals

A recent evolution of the tape loop is the looping pedal - a digital sampler built into an easy-to-use footswitch-operated pedal of the kind most often used by guitarists to create looping layers of melody or texture during a live performance.

A noteworthy example of this melodic layering effect is Ian Williams
