System for recording one's own voice on tapes already recorded with musical accompaniments

System enabling a user to record on commercial cassette tapes his voice accompanied by music, particularly music accompanying the voice of a well-known professional singer, already recorded by the manufacturer, comprising:

• recording means which enables the manufacturer to produce cassettes with dual-track tapes, so that the first track is recorded by the manufacture with musical accompaniments of songs, and the second track is left blank thereby allowing the user to repeatedly record his own voice singing along with the musical accompaniment recorded on the first track;
• and reproducing/recording equipment for the dual-track cassette tapes which enables the user to play back the musical accompaniment of the first track and simultaneously record his voice on only the second track;
• and
• wherein said reproducing/recording equipment includes an arrangement receiving two cassettes, said arrangement including one recess for holding an ordinary commercial complete one track cassette recorded with the musical accompaniment and the professional singer's voice, and another recess for holding the dual-track cassette tape on which only the accompaniment is recorded, said arrangement thereby making it possible to hear simultaneously the original rendering and the user's voice on the second track so that an immediate comparison can be made between the two renderings.
