Abstract
Abstract A music interpreter apparatus automatically interprets a notational music composition (written or printed music), which is abstract and incomplete to some extent, to provide its performance realization information which is specific and complete. The apparatus includes a score memory, an interpreter and a performance memory. The score memory stores a coded music notational symbol string representing a written music composition. The interpreter reads and interprets the coded music notational string based on an artificial intelligence simulating knowledge and experience of a human music interpreter or performer to provide a performance symbol string specifying the performance realization and containing played pitch, note-on time, duration and loudness parameters of specified values with respect to each note in the music composition. The resultant performance symbol string is stored into the performance memory.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
113 words
An apparatus for interpreting a notated music, comprising: music symbol string storage means for storing a string of coded music notational symbols which represent a written music, said string of coded music notational symbols being vague to an extent that musical interpretation of said string is required for its performance realization; and interpreting means for interpreting said string from said music symbol string storage means to provide performance data which specifies a pitch, note-on time, duration and loudness, of each note to be played and which is thus specific to an extent that an automatic performance of said written music can be realized based on said performance data without any further musical interpretation.
