Method and device for transforming musical notes

Claim 1

A device for transforming musical notes, comprising: a first original music memory means for storing the notes of the melody of a piece of music, a second original music memory means for storing the notes of the chords of the accompanying harmony of the piece of music, a first transforming memory means for storing rules for transforming the notes stored in said first original music memory means, a second transforming memory means for storing rules for transforming the notes stored in said second original music memory means, a logical processing unit including: means for reading first notes from said first original music memory means; and means for automatically transforming, about one of two respective fixed predetermined axes of transformation, said first notes to other notes in accordance with the rules for transforming notes stored in said first transforming memory means, and means for reading second notes from said second original music memory means; and means for automatically transforming, about the other of said two respective fixed predetermined axes of transformation, said second notes to other notes in accordance with the rules for transforming notes stored in said second transforming memory means, wherein the rules stored in said first transforming memory means and the rules stored in said second transforming memory means are such that every key of the standard keyboard is associated with its mirror-symmetric counterpart with respect to one of a Re key and a Sol♯ (=La b) key, said Re and Sol♯ keys being said fixed predetermined axes of transformation, whereby the basic sequence of notes Do, Re, Mi, Fa, Sol, La, Si is transformed into the counterpart sequence Mi, Re, Do, Si, La, Sol, Fa, and the symbol "sharp" (♯) is transformed into the symbol "flat" (b) and vice versa; a first transformed music memory means for storing the melody notes transformed by said logical processing unit, a second transformed music memory means for storing the chord notes transformed by said logical processing unit, and music performing means for performing said transformed notes stored in said first and second transformed music memory means.

Claim 2

A device for transforming musical notes, comprising: a first original music memory means for storing the notes of the melody of a piece of music, a second original music memory means for storing the notes of the chords of the accompanying harmony of the piece of music, a first transforming memory means for storing rules for transforming the notes stored in said first original music memory means, a second transforming memory means for storing rules for transforming the notes stored in said second original music memory means, a logical processing unit including: means for reading first notes from said first original music memory means; and means for automatically transforming, about one of two respective fixed predetermined axes of transformation, said first notes to other notes in accordance with the rules for transforming notes stored in said first transforming memory means, and means for reading second notes from said second original music memory means; and means for automatically transforming, about the other of said two respective fixed predetermined axes of transformation, said second notes to other notes in accordance with the rules for transforming notes stored in said second transforming memory means, wherein the rules stored in said first transforming memory means and the rules stored in said second transforming memory means are such that every key of the standard keyboard is associated with its mirror-symmetric counterpart with respect to one of a Re key and a Sol♯ (=La b) key, said Re and Sol♯ keys being said fixed predetermined axes of transformation, whereby the basic sequence of notes Do, Re, Mi, Fa, Sol, La, Si is transformed into the counterpart sequence Mi, Re, Do, Si, La, Sol, Fa, and the symbol "sharp" (♯) is transformed into the symbol "flat" (b) and vice versa; a first transformed music memory means for storing the melody notes transformed by said logical processing unit, a second transformed music memory means for storing the chord notes transformed by said logical processing unit, and music performing means for performing said transformed notes stored in said first and second transformed music memory means.
