Abstract
Apparatus and method for easily, efficiently, and accurately searching melodies. A melody is inputted to a computer and converted into a form of a sequence of digitized representations of relative pitch differences between successive notes thereof. A melody database is searched for at least one sequence of digitized representations of relative pitch differences between successive notes which at least approximately matches the sequence of digitized representations of relative pitch differences between successive notes of the melody.

Apparatus for searching a melody comprising a computer means having a database of melodies each including a plurality of notes in a form of a sequence of digitized representations of relative pitch differences between successive notes, means for inputting a melody to said computer means, means for converting the melody into a form of a sequence of digitized representations of relative pitch differences between successive notes thereof, and means for searching said melody database for at least one sequence of digitized representations of relative pitch differences between successive notes which at least approximately matches said sequence of digitized representations of relative pitch differences between successive notes of the melody.
A method for searching a melody comprising the steps of:
- (a) selecting a computer means having a database of melodies each including a plurality of notes in a form of a sequence of digitized representations of relative pitch differences between successive notes, (b) inputting a melody to the computer means, (c) converting the melody into a form of a sequence of digitized representations of relative pitch differences between successive notes thereof, and (d) searching the melody database for at least one sequence of digitized representations of relative pitch differences between successive notes which at least approximately matches the sequence of digitized representations of relative pitch differences between successive notes of the melody.
