Abstract
Abstract In an automatic arrangement apparatus, a melody of a part of an original musical tune is memorized in a melody memory (4), chord data of the original musical tune is memorized in a chord progression memory (5), and a rhythm pattern in a rhythm pattern memory (12) is selected in accordance with the style and composition of the original musical tune. At a timing of a note code of the selected rhythm pattern, a top-note, an additional tone, a bass part and a drum part are produced. The top-note is produced by referring to a top-note table stored in a top-note table memory (15) and corresponds with the chord. The additional tone is produced in accordance with the top-note and the chord on a basis of a voicing table stored in a voicing table memory (16). The top-note and additional tone can be selected at a continuous two-tone pair.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
An automatic arrangement apparatus comprising: input means for applying arrangement data for arrangement of an original musical tune to a processing system of the arrangement apparatus, the arrangement data including at least musical style data and chord progression data; memory means for memorizing a plurality of rhythm patterns which correspond with at least the musical style data, the rhythm patterns each representing only tone generating timing; selection means for selecting a desired rhythm pattern for arrangement of the original musical tune from the memorized rhythm patterns in accordance with the musical style data applied thereto; tone pitch data meads for supplying tone pitch data indicative of an available pitch for the original musical tune on basis of the chord progression data; means for reading out the selected rhythm pattern from said memory means; and means for producing performance data based on the tone generation timing of the selected rhythm pattern and the tone pitch data.
Claim 2
Dependent Claim
155 words
