Abstract
Abstract A pair of recordings are synchronously reproduced, wherein one such recording suitably comprises a musical selection with which a student may correlate a response, while the second recording represents an ideal or correct response. The student hears the first recording continuously, but the second recording becomes audible to him only at the instance of his response coinciding with the information on the second recording. The student is thus given an immediate indication of the correctness of his response for the purpose of reinforcing the student''s performance. Also, an overall indication or summary is provided of the student''s ability.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
167 words
An apparatus for ascertaining the correctness of a student''s pitch, comprising: means for generating a musical sequence and audibly presenting it to said student; means for generating a reference sequence of electrical signals corresponding to a sequence of pitches representative of a desired student''s response to said audible musical sequence, said reference sequence and said musical sequence being simultaneously generated such that said reference sequence and said musical sequence are properly time related to provide a correct performance of said musical sequence and said reference sequence; means for receiving a sequence of pitches performed by said student and generating a sequence of electrical signals corresponding thereto; means for comparing said reference sequence of signals and said student performed sequence of signals continuously on a pitch by pitch basis; and means for instantaneously indicating on a pitch by pitch basis whether the frequency difference between said student signals and said reference signals is within predetermined limits, thereby indicating whether said student has correctly performed said sequence of pitches.
Claim 2
Independent Claim
167 words
An apparatus for ascertaining the correctness of a student''s pitch, comprising: means for generating a musical sequence and audibly presenting it to said student; means for generating a reference sequence of electrical signals corresponding to a sequence of pitches representative of a desired student''s response to said audible musical sequence, said reference sequence and said musical sequence being simultaneously generated such that said reference sequence and said musical sequence are properly time related to provide a correct performance of said musical sequence and said reference sequence; means for receiving a sequence of pitches performed by said student and generating a sequence of electrical signals corresponding thereto; means for comparing said reference sequence of signals and said student performed sequence of signals continuously on a pitch by pitch basis; and means for instantaneously indicating on a pitch by pitch basis whether the frequency difference between said student signals and said reference signals is within predetermined limits, thereby indicating whether said student has correctly performed said sequence of pitches.
Claim 3
Dependent Claim
42 words
An apparatus as in claim 1 wherein said means for generating said musical sequence is a tape recorder playing one track of a tape and said means for generating said reference signals is said tape recorder playing another track of said tape.
