Abstract
Abstract Bar codes representing sound information are printed on a marginal portion of a score. Prior to the performance, these bar codes are read out by a bar code reader, whereby chord data represented by these bar codes are successively stored in a memory provided in the body of a musical instrument. At the time of the performance, accompaniment sound corresponding to the stored chord data is automatically added to the melody performed by the player.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
185 words
A bar code recording and reproducing system comprising: a medium on which is recorded bar code information which includes at least code table areas containing a plurality of code data, table reference areas containing a plurality of symbol data corresponding to respective ones of said code data arranged in a given sequence, and separator areas containing separator information and separating said code table areas from said table reference areas; a bar code reader for reading said bar code information recorded on said medium; discriminating means coupled to said bar code reader for discriminating code data information of said code table areas and symbol data information of said table reference areas by detecting separator information of said separator areas among the information read out by said bar code reader; and converting means coupled to said discriminating means and responsive to said information read out by said bar code reader for converting said plurality of symbol data read out from said table reference areas into a corresponding plurality of code data arranged in said given sequence according to the result of discrimination performed by said discriminating means.
Claim 2
Dependent Claim
185 words
A bar code recording and reproducing system comprising: a medium on which is recorded bar code information which includes at least code table areas containing a plurality of code data, table reference areas containing a plurality of symbol data corresponding to respective ones of said code data arranged in a given sequence, and separator areas containing separator information and separating said code table areas from said table reference areas; a bar code reader for reading said bar code information recorded on said medium; discriminating means coupled to said bar code reader for discriminating code data information of said code table areas and symbol data information of said table reference areas by detecting separator information of said separator areas among the information read out by said bar code reader; and converting means coupled to said discriminating means and responsive to said information read out by said bar code reader for converting said plurality of symbol data read out from said table reference areas into a corresponding plurality of code data arranged in said given sequence according to the result of discrimination performed by said discriminating means.
Claim 3
Dependent Claim
27 words

Claim 6
Dependent Claim
230 words
A bar code recording and reproducing system for an electronic musical instrument having sound producing means, comprising: a medium on which is recorded musical information in the form of bar code information which includes at least code table areas containing a plurality of musical code data, table reference areas containing a plurality of symbol data corresponding to respective ones of said musical code data arranged in a given sequence and separator areas containing separator information and separating said code table areas from said table reference areas; a bar code reader for reading said bar code information recorded on said medium; discriminating means coupled to said bar code reader for discriminating musical code data information of said code table areas and symbol data information of said table reference areas by detecting separator information of said separator areas among the information read out by said bar code reader; and converting means coupled to said discriminating means and responsive to said information read out by said bar code reader for converting said plurality of symbol data read out from said table reference areas into a corresponding plurality of said musical code data arranged in said given sequence according to the result of discrimination performed by said discriminating means; said sound producing means coupled to said converting means producing musical sounds in accordance with the converted sequence of said plurality of musical code data.
Claim 7
Dependent Claim
230 words
A bar code recording and reproducing system for an electronic musical instrument having sound producing means, comprising: a medium on which is recorded musical information in the form of bar code information which includes at least code table areas containing a plurality of musical code data, table reference areas containing a plurality of symbol data corresponding to respective ones of said musical code data arranged in a given sequence and separator areas containing separator information and separating said code table areas from said table reference areas; a bar code reader for reading said bar code information recorded on said medium; discriminating means coupled to said bar code reader for discriminating musical code data information of said code table areas and symbol data information of said table reference areas by detecting separator information of said separator areas among the information read out by said bar code reader; and converting means coupled to said discriminating means and responsive to said information read out by said bar code reader for converting said plurality of symbol data read out from said table reference areas into a corresponding plurality of said musical code data arranged in said given sequence according to the result of discrimination performed by said discriminating means; said sound producing means coupled to said converting means producing musical sounds in accordance with the converted sequence of said plurality of musical code data.
