Abstract

An electronic learning aid for interactive operation with an operator with capabilities for the synthesis of a tone or sequence of tones. The tone, in the alternative, is used to either prompt the operator to respond in like fashion or is in response to the operator'"'"'s input of a tone or sequence of tones. In this fashion the learning aid selects a tune to be synthesized and communicates this tonal sequence to the operator who responds by attempting to mimic the sequence. An alternate operation of the learning aid is for the operator to audibly input a tone sequence and for the electronic learning aid to attempt to mimic the sequence of tones.
