Abstract
An automatic performing apparatus for use in an electronic musical instrument stores chord name data and chord generation timing data to carry out an automatic chord performance. In spite of frequent variations of a chord during the progression of a music piece, repetitive storage of a same chord name data is not required so that the amount of stored data can be reduced, allowing utilization of a memory of a small capacity.
Claims26
An automatic performing apparatus, comprising:
- a recording medium carrying a record of chord data comprising chord name data indicative of a particular chord name included in a music composition and associated timing data indicative of plural different imings of generation of said particular chord during a progression of said music compositon, said chord name data being carried on said medium only once for all of said plural different generations of said particular chord;
- read-out means for reading out said chord name data and said timing data from said recording medium;
- chord name data supplying means for receiving said chord name data and said timing data from said read-out means and for delivering out said chord name data at each of the plural timings specified by said timing data;
- and
- accompaniment tone generating means for generating an accompaniment tone signal based on the chord name data each time that said chord name data is delivered out from said supplying means.
A recording medium for use in an automatic performing apparatus to carry out an automatic chord performance in accordance with a progression of a music composition, carrying the following functional elements:
- a chord data zone, comprising:
- a plurality of spaced chord name data regions each containing chord name data indicative of the name of a respective chord included in said music composition;
- and
- between each two spaced chord name data regions, a plurality of chord timing zones associated with the chord name data specified in the continuous chord name data region, each timing zone having timing data indicative of a respective one of plural different timings of generation of that particular chord during the progression of said music composition.
A recording medium for use in an automatic performing apparatus to carry out an automatic chord performance in accordance with a progression of a music composition, carrying the following records:
- chord data, comprising:
- chord name data indicative of the names of each chord included in said music composition;
- and
- associated with the chord name data for each particular chord, timing data indicative of plural different timings of generation of that particular chord during the progression of said music composition, and wherein:
- chord name data for a particular chord name is carried on said recording medium only once regardless of the total number of generations of that particular chord during said performance.
A recording medium for use with an automatic music performing apparatus, said recording medium comprising:
- an elongated recording medium strip, there being situated on said strip;
- a plurality of contiguous zones along said medium strip, each of said zones having a first region containing machine readable indicia in the form of chord name data specifying the name of a chord, and a set of adjacent second regions each containing machine readable indicia in the form of timing data specifying a respective one of one or more occurrence timings in a musical performance of a chord having the chord name specified in said first region,
- said contiguous zones being spaced along said medium for sequential machine readability.
An elongated recording medium adapted for use in an automatic music performing apparats, said elongated medium comprising a first zone storing machine readable indicia specifying melody note pitch data for a musical performance, followed by a second zone containing machine readable indicia specifying melody note duration, and thereafter a plurality of third zones sequentially spaced along said elongated medium, each of said third zones containing a first region having machine readable indicia specifying the name of a chord, and thereafter a set of plural regions each containing machine readable indicia specifying respective plural occurrence timings in said musical performance of a chord of the specified chord name.
